The 550's were in the car when I purchased it. I just meant as far as doing mods since I purchased the car. But ya, I guess my settings aren't odd at all really. I was just looking at a few sample settings on the RRE site and one of them is as high as +39 for the 1k rpm lo setting. So I'll just continue doing what I'm doing to get the fuel trims zero'd out. Then I guess I'll start doing some 3rd gear WOT pulls and see what kind of results I get. Maybe you could give me some input when I post those results.
Thanks again for the timely response.
