I opened up the box that came with my engine to find MORE parts that I wasn't aware of. My engine came with the gas pedals from the '04 GTO, and now I just found a Bosch pump mechanism connected to a throttle cable and some kind of Bosch master box it plugs into. Now I'm confused as to if this is necessary to use in MY car or not. I'm guessing NOT, but then again, I'm wondering if this complicates my ECU reprogram and the harness mods. I have to call Speartech....not too sure WTF I'm supposed to do with it....or if it's even beneficial to use or a waste of time. Anyone ??
