Default JDM V8 EJ207 FP Green HTZ

When I was doing my initial research, I noticed that there weren't much EJ207 threads around with larger turbochargers. So hear goes.

The car was tuned by Corbin Johnson and I'm thoroughly pleased with the result. Corbin took his time to dial in the car things with nice results for a remote tune. Things were difficult from the onset given the low quality fuel and temperature conditions. Corbin brought the boost in slowing after 4800rpm and ramped it up to the end to help the power on top without being too taxing on the motor.

Initial lag as expected but it pulls hard until redline once the turbo gets moving. We recently started getting a local supply of ethanol so I might look into a flex fuel tune later on after I upgrade the clutch. I'm way beyond the limits of the stock 5-speed (it starts slipping on top after a few hard pulls).

Anyhow:

2500rpm of flat torque on a Subaru is beautiful. I know that pulls very nicely and the almost constant g's of acceleration in each gear means it grips/corners very well at full throttle.

Seams like a lot of boost for 400whp, but great curves otherwise!

Corbin. What'd you think of the green? So far I'm pretty biased towards it because price/power. It seems to be doing very well. The combination in wheel seems to be a sweet spot!

Thanks man,

Its a good amount of boost but its pretty conservative on the timing side of things.

So far, the logs come back incredibly clean. Zero FLKC, FBKC etc. Motor pulls smooth and clean till 7900rpm!

What is that, a dyno chart for ants? Care to enlarge that for us? I'm liking the shapes I see.

Unfortunately, 1080x682 is the largest resolution that VD will output.
