    Will that pcm still control the 4t80e transmission ?
    I am interested in the pcm if I can use it on my STS.

    Rolling start with a stock PCM vs a Standing start with a Shelby/LS1 PCM.
    Look at the starting spot and count the poles until 3rd gear

    If you put a blower on that thing and youre in the 12's now..........You will need large drag radials to get any traction at all, and you WILL be in the elusive 11's.......

    We have a new kid at work that details cars. He said don't kill your self in it.

    I have been driving sideways all my life. I grew up in SW Washington state. It can rain from time to time and cause slipery when wet conditions.
