Ever had a boost leak that wasn’t actually a boost leak? 👀

This turbo inlet hose was collapsing under boost, restricting airflow and killing performance. We swapped it out for a quality, reputable replacement and got this Subaru breathing properly again. 💨

This STI came to make some power… and it definitely delivered. 😮‍💨

This 2019 STI made 525HP on E85 with a Blouch DOM 2.5, Killer B header, PLM EWG uppipe, ETS intake & FMIC, GSC cams and valvetrain, ID1750x injectors, DW 430lph pump, and PTR flex fuel kit.

We tuned it on flex fuel + Speed Density via open source, running 22psi on 91 and 26psi on E85.

From pump gas to ethanol, this thing is ready to make power wherever you fill up. 🔥

E85 or pump gas? ⛽️ What should you tune for?

Devin’s answer: whatever fuel is readily available to you.

But if E85 is easy to find, it can be a big advantage. We typically see 40–60hp more than pump gas. 🔥

Just know that E85 usually means adding a flex fuel kit and, in most cases, larger injectors.

Here is our official podium qualifying lap that was run in heat 5 with a 57.488

Jesse did not expect this to be the fast lap as the car was still warming up (as you can see with how relaxed the entry to turn 1 was taken) We were actually .5 slower in the first half from our previous fastest lap and planning to go all out the 2nd lap.

But we were able to gain about 1.4 seconds in the back half!

Knowing this was all that was needed he did not do another lap and got off and started celebrating.

Dai had a major failure that morning.

Huge shoutout to Fortune Auto and helping the car stay planted through the corners with these amazing coilovers!

Day 1 of Gridlife at Lime Rock Park ✅

We got in about 4-5 hot laps today and ran in the 59’s on low boost and practice wheels/tires. Our practice sessions got cut short after a minor coolant leak and rain, but ready and feeling good for tomorrow and Saturday!

Time to throw on some fresh rubber and turn up the boost👊

Tune in tomorrow to watch us race!
Heat 1 - 9:20am (8:20am central)
Heat 2 - 11:30am (10:30am central)
Heat 3 - 3:25pm (2:25pm central)

This 2020 WRX came in for a complete flex-fuel setup and a

The build includes:
• MAP Intake & Catted J-Pipe
• Grimmspeed FMIC & EBCS
• COBB NexGen Flex Fuel & Fuel Pressure Sensor Kits
• DW340 LPH Fuel Pump
• Nostrum HPFP

We tuned it for 91 octane at ~20psi and E85 at ~19psi

With a 7,000 rpm rev limit it makes a smooth 370hp and 377 ft-lbs torque!👀

Would you run flex fuel on your WRX?
