Message I've also been through my sensors and replaced O2 sensors, Coolant sensors and Idle control valve recently. Those greatly improved throttle response.

I think my profile is mostly up to date (just updated with ASH piping). Yes this is with stock IC piping and ICs. I've got traction issues enough right now running 15psi, and I can't afford to run a stickier tire that will wear out faster. I'm starting to autocross more and my biggest problem has been that boost goes from 5-15psi very suddenly and that kind of sucks for DD purposes. I don't need any more power, but I want that power through a wider range of RPM. At 2k rpm I could floor it and barely go anywhere. 500 rpm later boost would start to pick up and at 3k I'd really be pulling and usually break traction. 1st gear was pretty much useless; either putt around or spin the tires. Now it's so much better. 1st gear I can actually get into it because boost builds much more smoothly. Point and shoot is so much better because I don't have to plan ahead for the power.

Being on a student budget I have to pick my mods carefully, because they're few and far between. Eventually I'll be getting ASH massives but all the power they'd unlock would be mostly useless until I can afford to run 150 treadwear tires all the time. For now I'm having a blast.
