anyone running a 3" or a 2.8" pulley with the stage 1 and injectors???? How much of a difference would there be between the stage 1 and 2 program with the smaller pulley?

The stage 1 and 2 programs are the same. You can run a 2.8 with it.

All the Stage 2 is is a Stage 1 kit with a 3.00" pulley w/hub, shorter belt, some bolts to put the pulley on and some funky looking bits for the bolts. It has the same paperwork that will include the same programming that you already have installed.

same program. running 2.8 with stage 2 is questionable. i used to.

I run a 2.9" with my stage 1 tune. Other mods. in my signature. I have not checked my AFRs, or my IDC....

you can definitely run a 2.8" pulley with the tune. from stage II to the 2.8" pulley, there is a noticeable power increase.

OK so I have the mods in my signiture and have had the GM stage 1 and 3'' pulley for about a month and 1st gear in the morning and not running the carr for a while bogs the car big time as if it is starving for some thing. I think iot might be with the spark plugs but when the engine heats up the car performs fine. shifting from 1st to 2nd sucks to . It feels like the car is ready to stall out . But like I said when the carr heats up it is fine but I'm confused if ti it the GM tune, the spark plugs or the clutch. Either way it is really annoying. I even thought that I did'nt havethe updated tune but ichecked it withthe GM dealer and they showed me and it was the new tune. Anyone have any thoughts?
