also, is your avcs working? looks like no. if not, you might want to try to wire it up. it won't effect the top end, but it'll give you A LOT more below 4,500rpm. i'd look into getting a JDM ecu and the IA avcs harness. either way, in a GC8, this car must fly.

yes the injectors maxed out, rev limiter is set to 7700 rpm.

as far as I can tell, avcs is not working since I am using brain crower 272 cams.

It seems to be spooling earlier than the previous tune, is this attributed to the addition of meth and leaner afr? You stated AVACS is not working correct?

that's right, avcs is disconnected.

spooling feels almost the same on the road, but keep in mind that the temperature and the humidity this time were much higher than last year.

Nice. Don't see to many 2.0Ls in the 500WHP ballpark. Congrats

Thanks guys,

The injectors are 740cc and rods are stock STI, have no idea about the duty cycle that was used.

That second torque curve looks so much better, throw some more fuel at it!
