I've been piecing together the stage 2 kit for my brother's '05 SS/SC and so far I have a used set of stage 2 42# injectors (30k miles on them) and a used stage 2 pulley (from GM kit). I know where to get the belt (crateenginedepot) but I haven't been able to find a part number for the GM stage 2 hub or the bolts that go with it. Anyone know where I can find these parts? Also if we install the parts will the dealership still do the flash even though we didn't buy the full kit? I know when I got the stage 2 kit installed on my old '06 SS/SC before I upgraded to my '09 SS/TC the kit came with some sort of access code to unlock the tune.

 

the dealership cannot do the flash without the code from the stage kit (it's in the instructions when you buy the kit). They need that code to call tech line to get them to assign the new program to the vehicles vin # .

 

So I guess the best way to go is just the stage 1 to stage 2 upgrade kit since I already have the injectors.

 

either that, or piece together an aftermarket kit....i.e. zzp pulley/hub, stage 2 belt, injectors (you have), and get a custom tune.

That's exactly what I was looking for, thanks! Now I guess all I need is to find a tuner. Is there a Trifecta tune for the LSJ? I know that there is one for the LNF and I've heard great things.
