Default Problem with my new mods!
OK, I changed my Supercharger pulley yesterday to 3.10" (was 3.40") and I didn't change the belt, installed LPE S\C CAI too.
Problem is the car wont run for one mile, suddenly shut down! The "Reduced Engine Power" light appear! I didn't tune the car for the new pulley or for the new CAI yet.. what do you guys think is the main problem? and I'm getting a new exhaust system, so do I need a tune for the new exhaust too? I can use all the help you offer.
Thanks!

MAF could be in backwards or the wires of the MAF are covered in oil from the air filter used by LPE CAI.

Nope, there's no oil I'm sure.

Predicted air table needs to be raised most likely, see your tuner.

Doug, do you mean the air flow is not enough? What about the exhaust? do I need a tune for it? can't the problem caused from the smaller new pulley hooked up with the old belt?

Why don't you try reversing the last mods you did. You know it was running fine before the latest changes. That should pinpoint the culprit.

Just taking notes. I am ordering a copy of HP tuner in the AM.

Think I may do my own ECS install and tune (w/ help I'm sure or a tow to NJ)

LPE CAI uses a 100mm MAF so it will not run right! GO TUNE IT PLEASE!
