Just installed my PFC last night. It was terrific to be able to read up on the forum and know exactly what to expect. Drove it around for an hour and had a fairly nasty hesitation on even mildly abrupt acceleration changes. Found cewrx7r1's recommendations for the acceleration enrichment, popped them in at lunch, problem solved....awesome!

Just wanted to take a second and thank everyone. After reading through posts, you see the same questions posted lost of times, but I was really impressed with the patience of those that know their stuff. Us newbies sure appreciate it!!!!

And I also wanted to let everyone know that's been posting "which ecu" type question that I'm highly impressed with the PFC. I certainly gave the AEM a lot of thought. On my old XS ECU, my car would stall every time I put it in gear, and I had a really nasty 3k rpm stumble. The PFC pointed out that my clutch switch is in fact faulty, but it doesn't even care. Rock solid idle, now. I'm already very impressed!
