From day 1 at the track, stock and with my predator I have a slow dead bog when I slam the gas down. I added 4.30 gears which were some help but had gear whine. Now I have 3.73 gears, predator tune (never updated) 87 and 91 no help. It's hot now but always about a 2.10 to 2.18 60'. Build it up to 2400 rpm and you can feel the car bind up. Try 2000 rpm and let it flash some might spin. But mainly I have a bog that feels like it takes a good 60-80 foot to start pulling. Stock converter is bad I know that. I added global timing, timing from 2-4000 not help. Next test I have a set of drag radials mounted today and will run it hard next thursday. Does it have too much fuel down low?? Any other thoughts?

My tuner told me to ease into the throttle and it would run better. I haven't been to the track in a while to try it but my 60' with just a tune were from 2.095 to 2.10.
I tried from dead stop to 2500 and not much of a change. I was getting beat at the line also but soon made the time up.

i have this also somewhat. my best 60' was 2.037 and now its higher due to weather i think2.07-2.09. my guy told me also to ease into it also at the line but wouldnt this hurt my times ? it does pull great when i do this method but havent tried it on the track.
