2.7" and GM Stage kit - good idea or not?
A little off topic, but is a 2.70" pulley safe to run with GM Stage kit on a daily basis? I've been hearing different stories. Anybody running smaller than a 2.8 with their GM Stage kit out there???

What if I swap in the 2.8 for the stage 2 pulley when I have my dealer install. Will the reflash automatically recognize this or do I still have to unplug the negative?

The reflash is just calabrating new air/fuel and other little fixes like sporadic idle while the A/C is on and what not.
compared to the 3"

Oh and where are the original bolts on the pulley??? I don't have any. Am I blind as a bat cause I was pulling on that thing for 30 minutes. Are you talking about the supercharger casing bolts?

I posted in the below thread too, but reply here too i don't care.

Be careful you dont screw the threads up in the snout of the s/c use anti seize on whatever you screw in there for lube

How to I get the hub with 4 bolts on the the shaft with a press? All the directions say is remove pulley with press. OK, thats easy. Then they say install new pulley with press and makes sure not to apply force to the supercharger casing. This step is what I'm talking about. I'm guessing I have to use the threads in the SC shaft to somehow pull the shaft through the new hub, but a normal press can't help with that. What the heck do I do?

You put it on with an installer tool, GM recommends an alternator pulley installer, but a lot have used 3rd party install tools for s/c's
