The first one had defective MAF screw threads, snapped a screw, got replacement after some *****ing (threads were not deep enough and wrong thread) got replacement pack of 4 MAF screws( it only takes 2) from dealer for $8, American Muscle really needs to update their install instructions, and tips, I got better ones from AEM site.
Sounds great and definitely better off the line, will see if any better mpg, had it up to 100 mph but ran out of road, lol
So far so good though, seat covers next!
P.S. no tune required for AEM
