was wondering if anyone has had their computer "upgraded" for better performance in their Hummer? I'm having a new AMG 6500 optimiser long block installed in my 1997 HMCS (extended warentees come in very handy) and was wondring if it is worth the $700+ some of the Aftermarket Hummer companys get for the upgraded computers? Or will a simple boost contoller (electric in my case)some high flow injectors, and a high output pump? Or will all this make the computer upgrade even more important? I wish some one would make a bigger turbo for the "G" van/ Hummer application.
