Testimonial – 2020 Subaru STi



2016 Subaru STi – ProTune

Took on this vehicle one evening as this client had bought a few performance parts from us and it was time now to have the STi calibrated.
Oh yeah the client did a phenomenal job in the install of all the items.

Mods on this vehicle were:
IAG air oil separator, Invidia up pipe, down pipe, CBE, 3port EBCS,
killer B pickup / windage tray, Perrin blow off valve, Cobb Tuning SF Intake, Grimmspeed TMIC, turbo inlet pipe and the pitch stop mount.

Have to say this was a very healthy motor and it showed as it was one of the highest EJ257 that I was have had the pleasure of calibrating with the practically stage2 mods on the vehicle.

2016 Subaru STi – RevWorks RW750 build

Local Subbie owner came to our shop after he had some engine issues with his vehicle. Car was previously worked by another shop and also tuned to what we see were stage2 mods.  Well we confirmed that it was down on 2 cylinders so in comes a call to our go to short block guys….Rev Works Inc.

After looking at the budget and the power goals of this vehicle the owner decided on a RW750_Stage3 short block.
We had to wait to finalize other projects and builds so with the patience of the owner we are finally in the middle of this project.  Here we leave you with some of the pictures of where we are at with this build.



More parts are arriving, as today the upgraded TMIC from Grimmspeed just showed up.

After the build of the engine and installation the car was treated to some #amsoil break in oil for the initial start. That oil was evacuated and then a second oil change with amsoil break in oil was inserted. 500 miles were put on that oil and then the car returned to have that break in oil evacuated. The Amsoil Signature series oil was installed and the tuning on pump 93oct began.
Shell 93 octane calibration at 20psi.
We are awaiting some speed density kit and an upgraded injectors to take
advantage of some ethanol E85R

2016 Subaru STi – RevWorks Short block install

A client came in one day to have his car calibrated.  As the dyno test was being done we noticed that the engine was not making the right power for the boost level that it was in.  After a compression test was made on this EJ engine, it revealed that a short block was needed.  Later it was discovered that the vehicle did not have the right calibration with the parts necessary for that level of power and psi that was being delivered to the engine.  This created a issue to the turbo and the oem turbo gave up the ghost. Along with the oem turbo getting damaged the engine lost compression in 2 cylinders.

Now that we needed a new short block in came the guys from RevWorks Inc.  Got together with Scott the president of that company and he guided me in the right direction to get this vehicle back on the road.  Took a few months to get the short block built and sent to us but it is finally in the shop and the build is coming together.  Here are the specs of the short block from RevWorks:

RW_EJ25_Stage2_ Block 100mm (RW600)

OEM STi Crank
Manley H Beam rods
ACL Race Rod Bearings
ACL Race Main bearings
Wiseco AP 100mm 9:1 Pistons
New Case Bolts (Mains)
KillerB oil pick up
ARP Headstuds / OEM full gasket kit

In a few days we will be having the new engine in the bay and ready for the break in procedure as per the RevWorks instructions.

3/12/19 – This is where we are at the moment on this build.  Hoping to get one item in to continue with putting all the parts back on the engine.



Slight Port matching and polish done in house for these TGVs.


2013 Subaru STI – Stage2 Calibration

Was the first day of fall, but with the ambient conditions that were present you would not think so.  Another hot and humid day in Kenner, LA.  We were working today with Scion tC as we installed a transmission on it and was adjusting the clutch on it and driving it on the street.

Got a call in the morning with a client that was wanting some one to look at his 2013 Subaru STi as it was not performing up to its standards.  Managed to squeeze the client in at noon and told him that we usually calibrate the cars at nights since it gets really hot in the shop.  He was coming in from MS and driving thru town on his way to Lake Charles and decided to call us to help him with his ride.

We moved cars around at the shop and got the AWD Dyno Dynamics ready for his arrival.  Placed the vehicle on the dyno and got it ready to see what we could do to help matters.

2013 Subaru STi with stage 2 mods:

Stock engine / Cobb intake, APv3 /Grimmspeed Upipe, TMIC and catback exhaust
Tial BOV with EWG / Air pump delete / Cobb Fuel pump

Ambient conditions were 103F / 43% humidity and 30.03 Baro
Test performed in 4th gear

The vehicle was previously etuned and the client wanted a dyno calibration instead so we proceeded to accomodate him as he had some DTCs present that needed to be taken car of which were affecting his fuel trims and his over all WOT fueling.

Before the dyno pulls were done we checked the oil level and also discovered that we needed to add a quart of oil to the engine. In comes some Amsoil XL series 5w-30 to the rescue.

Before and after resutls from the tuning session.  261awhp and 288awhp was achieved.

Dyno jet simulated number vs boost which just hit 20psi and tapered to 16psi.
In conclusions the client was very happy and we thank Chris for trusting us with his ride and having patience in this hot and humid day which was not easy day to calibrate an engine.
