How are you launching? I'm on 93 Goose Stage 2 and it feels pretty quick. My buddy has a Charger R/T and we were basically dead even from a stop. But when I tried it on my Dragy the best I got was 5.79 (5.47 w/ roll out). DA of 2132ft, 82F Temp. And that was in 2wd! 4A was worse. (Maybe its because I have Deavers?)I don't know how accurate the COBB timer is . I use Dragy which is pretty much accurate . 0 to 60 4.79s actual with 4.52s with roll out like magazines test . E20 fuel on Cobb Stage 2 OTS 93 tune .
I know the Dragy is accurate because I got 3.07 with my tuned RS7, or 2.85 w/ roll out. Exactly in line with what it should be getting.
