Hmmm, I have also been dealing with a running rich condition after switching from a single wire O2 sensor to a heated multiple wire sensor. I can't see how I could have gotten it incorrect. I thought it was from the removal of the cat since I also installed the same hooker long tubes and did the full exhaust change out. I will have to go back to the drawing board and figure this one out. Any advice anyone has would be appreciated. thnaks, gary

How muched does it cost to get it tuned? Just curious, did you just find a good auto performance shop, do they have to dyno it to tune it? Not sure how it works on injection.

Dont know about other header installs nor their power output. I di know the Headman headers I bought for my 86 from Summit, didnt fit worth a crap, One of the tubes I had to almost beat to half its size for clearance.
