16.6 @ 77 MPH

I would have the computers reflashed to stock and then go from there (tune).

Wow, I ran faster than that in my old 3.4 Camaro. I wish I could drive your car to get more of an impression of what the hell is happening.

Were you sitting at the tree with your foot on the brake and the gas pedal on the floor? I would think you probably broke something doing that. I know how to flash auto's even though im a M6. But ya you definately have something very wrong.

Damn I hope I didn't "F" something up. If I did break something what could it be? The car still drives fine on the road. It still gets up to speed on the highway. At light throttle I can get up to 100mph with no issues, fairly quick. It's only at WOT is when the car feels like a minivan and I can't launch. At the tree I floor it and the rpm's soar but the car feels as if it has a trailer attached. It feels like this the whole way down the track.

probably because you're spinning the whole way down the track...what tires are you running?

I have the stock 16" tires. I figured I'd get some drag radials later. I just recently put the mods on. I had my girl watch me at the line and she said my tires did not spin at all. What else could be going on?

lol, you launched out of the hole at 2500 rpms on stock 16" tires and you didn't spin? i wouldn't trust your girl on this one. i went to the track last night. it was prepped horribly (90 degrees and 100% humidity didn't help either ). i have 2.73's, 275/40/17 tires and launched at 1500 rpms and spun so hard, my transmission shifted into 2nd gear, then i caught traction and it downshifted back into 1st. i ran a 14.4 @ 105 mph. holy ****.

i'd bet dollars to donuts you were spinning. either that or your shift points are completely screwed, or you have the worst knock retard at WOT known to man

are you running 91+ octane fuel?

I doubt he's spinning the tires if he said he didnt and his girl said he didnt. Even if you did spin you still still have a good trap speed

Well, I'll be giving it another shot this Friday. This will be after tuning but it still feels the same as before. Should I just hit the gas at the line or stall it again?

I want to but the best place to dyno is about 6 hours from here (TSP). Many people on this board and in town don't really trust the local speedshops around here. I've heard too many horror stories.

^^ yea, i think it would be worth the trip tho, a bolt on tune should cost around 250 or less, and then hopefully the ride back will be alot more fun than the ride there, but honestly its prolly your best option... hell make a cruise outta it get some people to tag along...

EDIT: when you had the new tranny / torque converter installed, did you have your torque management deleted?
