[QUOTE="turbov6joe, post: 9911979, member: 95661"] I ran an Alky Control kit on my turbo Regals for many years, and did a LOT of test-n-tune with it to get it dialed in. I along with Eric Marshall (Turbotweek) made countless hits on the track as R&D for his alky chips. I agree with you that the ramp should be more aggressive with a blower car. However, keep in mind that with pump gas alone, you should be able to run ~18 psi. What your trying to do is add just enough octane (meth or alky) to compensate for the extra few psi/timing your wanting to run.
