anybody using Fast Sequential System??
That said, it offers a neat style of tuning that is different than the stock PCM. Don't ever let anyone tell you that it is more powerful, just different. The factory PCM is awesome in it's own right, but a little more difficult to get right with a wild combo.
If you have a street car that you care to drive around at all in, my suggestion is to go the LS1_edit route and keep your car liveable. If it is going to be a race car that just needs to have the engine controlled, then F.A.S.T. is a fantastic product that will be easier to tune than most any other option (especially if you spring for the WB02 option).
