Why is it I have a "decent" time (8.1) in the 1/8 but everyone is KILLING me on speed? My best speed is in 82.4 MPH. Mods in sig. My guess is it may be my tune. The last trip I used the OBDI PCM but I was had the stall wall problem so it was hard to tell if that helped any. My times before I broke 7 teeth of the ring gear (guess the 10 bolt didn't like the 1.7-1.8 60's ) were 8.2's on the OBDII and on the OBDI switching from 1-4 after letting out......8.7's. What would make my speeds so slow?? It weighs 3530 empty. (no driver)
