Did your tuner take out some of the TM on the engine side? Prior to my tune my best was a 2.07. My worst after the tune was 2.06 but out of the 5 runs made last Friday night I had 1.98 and 1.99. I'm still trying to find that perfect launch technique but I have been trying to find that all year and last Friday I have been doing what I always do. That is almost a tenth improvement.
Last Friday night this was my setup. 28psi cold in the rears. At the line load the rearend up, between 1000-1300rpms then squezze the throttle on the last yellow. Of course this is with an auto. Still trying to find the best launch rpms. Also may be able to improve it with lower air pressure.
While track prep may have been different I doubt it. The weather was very much like the last time I ran in June, maybe just a bit warmer, 5deg. It is always the same crew at the track. But who really knows. Anyway I'm happy with the direction the car is going in.

On my A4 if feels like a prolonged shift and my 60 foots are around 2.0

No not really, just making a joke. I know how AH and ABS work. When I launch I do not engage those systems. I understand them enough that I know they don't slow me up.
I do not launch with lots of build up RPM's and spin. I run mostly for consistency, so in the C5 the best method seemed to be launch from idle. But I am having better luck with my C6 just loading up a little 900 to 1000 rpms. But my wheels are arrow straight and I don't spin so my AH is not doing much, if anything. My ET's with comp mode and everything off are identical.

I really do not know enough about it to tell you what he did to be honest. But I have enough runs in the C5 and C6 that I can feel it when I launch, and it is not the brakes, not on my launches. I know what you are talking about with AH can slow you down on a launch though. Not disagreeing.

Again you all are trying to make a road race car into something it wasn't intended for and to take a 3200lb machine to go from 0 to something in almost time zero without something having to change is way out there. Do you think the rail dragsters with thousands of horse power pull timing to keep the wheels from spinning and braking a drive train.

My vette is starting to bounce of the limiter more often. 3 times now at WOT I have hit the rev limiter going from 2-3rd.
It is a little bit of a dilemma. My tuner did not touch the shift points or the rev limiter. He told me with HP tuner you can not tune them yet.
So now I am wondering what I can do about it. I may have to go to the dealer and see if he can move shift points. For that, I would normally have the stock tune put back in before I take it to the dealer.
Sucks.

Check out this link to that tuner's website (click on Torque Mang.):
Cartek TM Eliminator
If you notice, it says: "This unit is designed to help prevent the ECU from reducing timing and throttle angle (torque management) under hard driving conditions and fast shifts".
Now I don't expect them to tell us all their proprietary info on how everything they sell works, so if TM does do something with ABS, that may be part of what their module does.
Butt......if they are saying that their module does something to stop the car from pulling timing and reducing throttle, then I would guess they believe that timing and throttle are involved in whatever the General designed into TM.

Beezeye, wouldn't waste the key strokes trying to post any objective info on the Cartek TM-module. Several of the engineering-challenged squatters on this thread long ago ran off Julio, master-tuner and owner of Cartek. Julio attempted a little education. But the engineering-challenged hooted him off the thread because they "know far more" than Julio and demanded he reveal his proprietary technology.
Quite breath-taking behavior from non-engineers, non-racers, non-wrenchers. But that's all months ago and a period on the thread that's best not repeated.

I really don't mean to be rude, I am just very curious. I respect your postings and especially respect your ET's.
Thanks,
