Chris, if you were blowing thru your old converter at the track, it may now be the same or faster than it was. Glad you are running again. In first gear, when are you at full boost? With that t-6 1.32 a/r, i dont usually see full boost in first on the street....not enuff load. I put a smaller wg spring in so my wife can run it down the track...now i can go down to like 6.5 psi
