I just got done installing an asp pulley. The car is now running really rich even after reseting computer and driving it 60 miles. Is this a normal condition and is there any way to fix this besides getting a tune. Also the same time as the asp install I also descreened the maf. Is it possible that it could be contributing to this mystery. Please help need input.

Are you sure it didn't start running rich after installing the headers? Most LS1s run rich after headers without a tune. If not, more likely had to do with the MAF descreening that the pulley. Get a tune, you'll pick up some hp if you're running that rich.
