Best pass was a 14.06 (97mph) with a 2.02 60ft. Im power shifting at 6000rpm. Clutch isnt slipping. With my mods I should be in the mid 13's dont ya think? I know I need an upgraded MAF but still. Could I be running lean or somehting? My car runs great unless I turn on the A/C then it idles like crap and dies after a while. I changed the TPS and Idle air control. Didnt help. No codes are showing. Im guessing I need a tuner to see whats up, any suggestions? Oh and I have to shift into 4th in the last 100-150 feet or so or the damn rev limiter kicks in which I know is killing my times.

Your shifting too late, shift at 5800 in first, take second & 3rd to about 5700 and you'll pickup some time. Your 60's are good but your MPH is low. If the MPH doesnt pickup to close to 100 then theirs something wrong. What was your DA? Times are relative to DA. I'm voulunteering your for the timeslip section too

why do you think shifting at 5500 would help me?

mdvaldosta

im in the chat...

your powerband falls off after 5100 or so, even with those mods... holds pretty flat till 5500 or so and starts falling after that...

you wanna be in the best powerband... you make more power at 4500 than 6000

peak hp is 5650 or something, peak torque is at 4000, so your losing everything past 5650

more like 5,250...
