Procharged Coyote Build

We’ve done Mustangs with Prochargers before, but this one is a little different. The owner brought us the car with the Procharger already installed and wanted to do a little twist on it. He wanted an smaller diameter pulley for more boost, but a waste gate on the intercooler piping to regulate boost pressure, and allow for a better torque and turning a procharger into a TORQUE MONSTER.   With this kind of setup he will be able to run different amounts of boost up to the max psi that the pulley produces.

dsc_0233dsc_0239dsc_0228Placement of the red Tial blow off valve and wastegate was definitely important. From the outside others had to know that this Mustang was something special. We decided to mount them on each side of the intercooler so that they’d show in the lower part of the front bumper. Their red color definitely makes their presence known.


dsc_0555The small diameter pulley can produce about 20 psi of boost, but the wastegate will be able to regulate it. The Tial  BOV is located under the MAF on the left side of intercooler,  which Would cause distorted readings.  To solve this, we relocated the MAF to the cold-side intercooler pipe. we also added a PMAS Hpx  Frequency Maf to allow the proper scaling for this setup  This smoothed out readings and allowed us to get accurate data while tuning.

dsc_0576While we were under the hood, we upgraded the crank sprocket and oil pump gear as preventative maintenance, since they are known to fail. Once all of the fabrication was done, it was pulled onto our Dynojet for some tuning.

dsc_0637editdsc_0679editAfter some work on the Dyno this thing laid down an Impressive 702whp and 575wtq at 13 pounds of boost. The tune was Done through Hp Tuners.  The blue lines are from the previous tune with the procharger before the smaller pulley and other modifications we did this time around. It’s definitely a substantial increase in power

TUNED: Camaro SS

The shop was rumbling thunder yesterday with this rowdy Camaro SS on our Dynojet. It arrived with an aftermarket intake and exhaust installed and we unlocked the true power potential hidden under the hood.  As you can see, a good tune goes a long way in maximizing the effectiveness of your modifications! Bring your car to PSI and let us unleash your cars final form!

Baseline: 320WHP / 318 ft-lbs
End result: 360WHP / 344 ft-lbs


TUNED: Sweet Lou’s S13

Lou brought his S13 by for some love to get it on the track this weekend for a drift event.  Before getting down to tuning, we did a  proper break-in session on his freshly built SR20.  Several miles going through varying load patterns on our Dynojet allows for the ideal conditions to ensure a new motor’s longevity.

We set his power at a safe level given that the fuel system was running out of headroom and he will return after the event for more mods and even MORE POWER! The end result will be an easily obtainable and track reliable 350WHP.


TUNED: Brian’s Focus ST

Brian brought his Focus ST to us for one step colder plugs, a few small tweaks, and a retune. We wrapped the inlet pipe with high quality Mishimoto gold reflective tape to reduce inlet temperatures. For the money you can’t beat the performance of this ST!

-Mod highlights: Cobb intercooler, intake, charge pipes, turboback, and Accessport

End result: 274WHP / 360 ft-lbs

200WHP N/A LS/VTEC Integra tune

This Integra came in a while ago with the LS/VTEC conversion already completed. It had a few issues and dynoed in the 150-160WHP range. The owner then picked up a new exhaust, installed Acura RDX injectors, a Walbro 255 fuel pump, & brought it back in for a retune. Using Crome, we tuned it to put down 197WHP with ease. Seeing no reason to push every last ounce out of it we left it at this conservative level in anticipation of a Skunk2 throttle body, cams, and intake manifold.

This is another car that may not have put down a lot of power, but shows what the right parts and good tuning can do. The next round of mods will put this well over 200WHP which will make this already fun car a blast to drive on a daily basis. Check back for updates soon!

If you’re looking for work to be done on your car or getting a custom tune contact us at the shop! With this nice weather everyone is on a mission lately.


RB25 single turbo swapped S13 240sx

Here we have a S13 240sx with a legendary Skyline RB25 engine swap. Along with the swap the car is running full supporting mods & a single Garrett 55mm turbocharger. Let me just say, the looks of this car may be controversial with the bright metallic blue paint, widebody body kit, old school non “fitted” wheels, and non “stanced” suspension, but there is no denying the sound & power the RB25 engine produces when modified correctly.

The car was a pleasure to tune & listen to until some small problems arose. The car was running an “ebay” turbo kit with a legit quality Garrett turbo. The external wastegate that was installed wasn’t functioning properly causing severe boost creep the higher the RPM’s climbed. While we wished the car was equipped with higher quality parts to help produce the true potential of this setup there was nothing we could do at the time. To make the best of this situation, boost was set to 14psi and revlimit was set to around 6,500 RPM’s. With keeping max RPM’s here it kept the boost from soaring up to unsafe levels.

Once again this proves that you should use quality parts when modifying your car. Luckily we were able to reach the 340-350WHP goal the owner was looking for, even though we really wanted to make 400WHP with this setup. If your looking to have your car tuned give us a call at the shop! You won’t be disappointed, our tune results & customer satisfaction speaks for itself!

Enjoy the sound of this JDM swapped beast:

1JZ Supra swapped 350Z!!!

Where do I start on this unique…controversial heart transplanted Nissan 350Z? I guess i’ll start with the background. After running multiple VQ35 motors (n/a as well as turbo setups) the owner of this 350Z was tired of having expensive issues and wanted to try something different yet more reliable. So in went the 1JZ 2.5L turbo Toyota Supra motor which has been known to be rock solid over the years.

The car was dropped off to us with the motor in the bay, some wiring done, but overall in need of a lot of work. We built a custom intercooler setup for the car utilizing a Tial QR bov, custom intake, and a full 3″ exhaust that steps up to 4″ in the rear section giving it a unique sound to go with the unique engine swap. After finishing the wiring & other miscellaneous odds and ends we fired it up and boy did it sound wild.

For now, the owner is leaving it stock ecu until funds allow more upgrades so we decided to do some basic data logging on the dyno before it leaves the shop. So stock ecu, stock tune, stock boost with the above mentioned mods left us at 290WHP & 280wtq. We would love to get a tune as well as a few more pounds of boost in this thing, but for now its a responsive fun ride that makes more wheel horsepower then a bolt on VQ35 that originally would of came in the car.

These are just the type of projects that we enjoy here at PSI PROformance, whether they are loved or hated on. We take pride in doing the work other shops can not complete & putting out quality custom fabrication work which can be seen here. Enjoy the video below and don’t hesitate to contact us to get your custom project underway!

Turbo Integra GSR DA tuned

It’s not often you see Acura Integras of the DA era around anymore. Forget seeing one in general, how about a GSR model, that’s clean, turbocharged, and makes 250whp!?!? This Integra is running the original B17 VTEC motor (134k miles on it) along with an Ebay .50trim turbo, FMIC kit , Drag exhaust manifold, and 550cc injectors. The car rips for only making 250WHPat 8psi.

Now many people may think that is “low” for a turbo Honda on a .50 trim, but lets remember this is on an original motor and get this, an original STOCK FUEL PUMP. The pump will be switched out for a Walbro 255 unit & a few other small changes will be made in the upcoming weeks. The owner will then bring it back in & were hoping to see around 300WHP depending on the conditions. The tune is safe, reliable and makes strong power under these circumstances to hold over until more mods can be completed. For now enjoy the video of it at 8psi, and don’t forget to check us out on Facebook for updates on this car and all of the other projects going on at the shop!

RX-8/MS3/MS6 etc. MazdaEdit ECU-Flash tuning!

We are proud to announce that we have been tuning newer Mazdas directly with the factory ECU for a little while now. We all have seen this in the EVO/STI world, which made things a breeze for the customer & tuner when working on the car. Also many weren’t happy with the second-hand middle man tuners that were the only way to tune the cars in the past, but that is all behind us now. If you own a newer Mazda and are looking for a tune please give us a call so we can discuss it more directly.

One of the cars we had in for a MazdaEdit tune was this RX-8 rotary with a K&N intake and stock exhaust running a test pipe. These are known be to overrated on the quoted factory horsepower numbers & this one was no different. After tuning the car it put down 155whp & 113wtq which was a 20+ whp gain from stock. A few more mods to help it breathe would definitely increase these numbers, but for basically being a stock car with a tune these are great improvements.

Again, if your looking to get your Mazda tuned give us a call. Our real dyno numbers & customer satisfaction speaks for itself!

430whp built Audi A4 tuned!

We don’t often do Euro cars here at PSI PROformance, but when we do its usually a very unique or big build. This Audi A4 1.8l turbo is no exception, and has been one of the owners main projects for years. The workmanship & time that has gone into the engine bay really shows. Only the best of the best was chosen such as a Full-Race turbo kit, a FP HTA30r turbo, JMF one-off intercooler kit & custom intake manifold, along with the built & stroked engine.

With this group of parts, and a 034 Motorsports engine management system the car made good power with ease. On pump gas 93oct, low boost (24 psi), and a conservative tune it laid down 430whp on our in-house awd Dynojet. This setup isn’t even breaking a sweat and is exactly what the owner wanted out of pump gas without pushing it hard.

As you will see in the video the trunk and rear lip aren’t color matched to the rest of the silver exterior. It is one of the only things left to “complete” on the project which the owner is taking care of as we speak. The owner is excited to get the car finished for this upcoming season now that it can be driven anywhere, fill up at any gas station, and be driven reliably. Once the body work is done it will look as good as it sounds & runs. Soon after that completed the car will be coming back in for a re-tune on race gas,  so it can safely crack over 500whp. We look forward to having it back in the shop, as well as the next unique Euro project that rolls through the door! Contact us today to get your build started or tuned.
