help with af ratio.....

[nastyvega]

this may be a stupid question for most of you guys, but im new to turbo buick tuning. I was wondering what would be a good air fuel ratio at wide open under 25lbs of boost. ive got a turbotweak chip and im currently showing a 10.3 reading on my wideband. was wondering if I could safely lean it out via chip settings/fuel pressure reg. what would you guys suggest on a safe tune???? dont want to be on the boaderline of blowing her up!

Are you running alky?

10.3 is a fat tune; I'm assuming you have no knock, and the car is running is tip-top condition.

I'd lean it out a bit in the chip, make a run, and check your results.

thanks for the quick reply. i am running alky and it is running tip top. would 11.4-11.6 be a safe ratio?

Every car will like something a little different but on ALKY most run good with AF in the 11's I shoot for 11.2 to 11.5
