My AFR goes form inital WOT 12.5AFR to full boost 11.5AFR
I'm using an AEM wide band AFR gauge at all times when drivin gmy car. I also have on order the Andial Intercooler temperature gauge to keep an eye on my intake temps. Should be 130*F or lower. My intercooler keeps that in check.
I want to do some more extensive tuning on my car getting a tighter AFR of 12.5-12. I need to find a dyno that is sutiable for the air cooler 993 engine.
Anything close to 13AFR I'd be scared! When I was using the Split second box on my 993 when it was stock I have AFR spikes of 14! Way too lean. Engine bogged and felt like _ _ _ T. All the tuning in the world couldn't fix the problem. Ended up going Unichip and things are great now.
