Between forum posts and the book from Greg Banish I thought I would have enough knowledge to start tuning. I might be wrong. I had a 09 Corvette with an LS3 and a manual trans. The car is stock besides my recent mod of adding Speed Engineering Headers, X-Pipe without cats, all attached to the stock NPP exhaust with the fuse pulled. I bought an AEM AFR gauge and got it to log and finally had a chance to do a pull. Attached is the log. I noticed it sightly rich throughout the RPM's at WOT and also 1.5 and 1 degree or KR at 3 areas. Nothing else seemed too far off. Tune is stock from the factory besides the downstream O2 CEL's being turned off.
I plan on doing the following.
1. in the EQ ratio, try and lean out the whole curve slightly maybe 2% and maybe 3% in the 4000-5500 RPM area.
2. Retard the timing 2 degrees in the 2 spots that I saw KR.
If i am anywhere in the ball park let me know. If I am totally off, I'd love an explanation as to why I'm wrong.
