I have been talking to a guy about buying this Supercharger kit for my 01 GMC Sierra Truck. He said it is complete except for the tuner. I have a U7198. Is there any way to upload the tune to my tuner or can I adjust my tune to work? I have already adjusted my injector slope to -7 and my PE to -8 to get my fueling numbers in line. Would there be enough room for adjusting for more? Maybee retard the timing a couple degrees. by the way, would that be going to the left on the scale or to the right. It seems like all the adjustment scales react the opposite of how I predict.

OK, you're not going to be able to tune for a supercharger with the Predator by itself. You'll need to get it custom tuned on a dyno.

If you buy the kit, post a copy of your current tune here with a list of all modifications and we'll set you up with a nice tune.

Okay, I bought the kit. I have the serial to usb adapter but for the life of me cannot get the programmer to communicate with my laptop. I live up the street in Lake Worth. Is there any way I could bring it by or is there somewhere else I could bring it where someone can download and upload to it?

Does anyone know what injector options I have? I would like to get a set of 42#. I see the Delphi Multec 2 44's are a direct replacement, but I cannot find them for less than $400. Will any other injectors work? Will I need a new fuel pump? Where could I find that?
