Hrobb256 Posted September 14, 2016 Report Share Posted September 14, 2016 have a 03 awd ss and taking it to a dyno is out of the question I know each setup is different but wondering what air fuel ratio is a good target for best power on these trucks? I was thinking about trying to shoot for a 12.2-12.5 if anyone has some dyno experience would be appreciated. im running small cam headers no cats cai Quote Link to comment Share on other sites More sharing options...
1BAD2K Posted September 14, 2016 Report Share Posted September 14, 2016 I would definitely talk to a professional tuner and have him "street tune" the truck. Quote Link to comment Share on other sites More sharing options...
Downeast Johnny Posted September 14, 2016 Report Share Posted September 14, 2016 Find you a good tuner, (Zippy), Let him know what your current mods are and he will set you up with a tune. In the future you can send him logs from a laptop and he can tweak and fine tune it. Quote Link to comment Share on other sites More sharing options...
chpspecial Posted September 15, 2016 Report Share Posted September 15, 2016 12.5 to 12.8 is a good target on good gas. Watch for lean kr. If you start to see it. Richen it up a bit. Also make sure your commanded and actual AFR match. If they don't. You need more tuning than just looking for a value on a wideband.

To the OP - Honestly, I saw very little performance gains going from 12.0 to 13.0 tailpipe AFR for a NA truck. I would target the range from CHP above.
