looks likean N/A set up ;-)
get rid of the rich spots,especially near 4100 rpm
lean it out all across to around 13 -13.5 A/F
you should pick up a few horses just by tuning it and car will feel much better

allrite ill get an safc next spring, how bad is it? really bad or kinda bad? how much more power you think i can get with proper tuning?

hamhead

Its not too bad, but the car does get rather rich toward the higher RPMs. As said, 13.0 AF would get you a nice chunk of power back.

What is the compression on the engine as of now? Still at where it should be, or is it weakened?

Looks like it was a bit warm during the dyno too eh?

ya it was in the 80's outside, inside was low 90's the temp said. fans were on engine but it was still hot. think i lost some there?

I'd partially blame it on the weather. It's all about cold air everything these days...

Its usually best to tune on for the hottest possible situation (especially if you are tuning to tight specs) this way no matter what, you will not have a detonation issue with temperature changes.

so when i get an afc and tune i should do it in 3rd rite? and i should make it about 13.0-13.5 the afc can have to maps rite? what should it be at for normal driving or fuel saving?

3rd or 4th gear
shoot for 13.5 A/F
