A/F readings

Have not been on in a while but most of you know my car.. It is running great but my gas mileage is so-so. I have a GT35 turbo billet wheel. I just touch the gas and I have 5 lbs boost. Great spooling turbo with EFI. My question is at low boost 5lbs and under I drop down to 12.5 to 12.1 A/F ratio. Is that right or can I lean it out alittle to save some gas.
THere is really no heavy load on the car at that boost level.
Thanks John

12.5 on boost is safe and appropriate. It's the AFR when cruising, which is most of the time in normal driving, that will gobble up your gas mileage. You should be at 14-14.7. And older cars are likely not to give as good mileage. MHO
