Awesome!!!! I can't wait to see what kind of #'s can be had with pcm tunning. I also can't wait to be able to modify the torque management tables. This should increase our 1/4 times by alot alone

I would hope it's been built to at least take the amount of power in the setup, "if were able to be unlocked"..is that asking too much?

It better hold up!! Maybe GM should have spent the money on beefier parts and not on the torque management program??? I think GM should unlock this feature for free when our warentys expire. If I want to break half-shafts when my car is out of warenty then that is my problem not theirs.

I'm pretty sure the tranny will take it but the other parts puttin power to the wheels - I doubt will for too long... that is, with sticky tires.

Shift points fixed yet or still early? did you take all the TMS out or leave some, and if so how will that affect those wanting to use DR's?
