Had my PCM replaced this week. To be completely honest
my car doesn't have the power it had before. I noticed a drop in boost.I've always got anywhere between 12-14 pounds, now it's 10 to 11. Big difference. Have no idea why. Sorry now that I had it changed,as long as I kept my plugs gapped tighter I had no problem. Thought I'd go for it since so many of you said it made a difference.
