My A-Spec 500R Kit Dyno Charts

I spoke to another owner of this kit and he is claiming actually slightly worse response in 3rd and 4th gear but marginally better response in 1st and 2nd? His car made around the same power at the same boost level, within about 10rwhp.

I havent seen many if any other dyno graphs or reports about this turbo. At this point I am lost on what is causing the slow response. Hopefully adjusting the Profec B will help dramatically. We will see I guess.

Kevin, I know the wastegate spring is 13lbs, when you had it running directly off the spring bypassing the Profec was response really any better or have you tried this since have it tuned?
