.....especially if you are using the free mod AFPR. I've got mine at about 12.5# now and it seems a little rich around 2500 RPM at WOT. Also, how are you guys doing w/ gas mileage at your current FP setting?

 

Well im running about 13 psi (what it was set at stock) with the lt1 cam, edlebrock performer tbi, pulleys, 3inch exhaust all the way, turbo city tbi with stock injectors, and an open element, it gets about 20 mpg without leadfooting it, this is all on the stock chip, but it does seem to run rich at idle..but my chip is coming at the end of this week so hopefully there will be an improvement..

 

Mine runs between 11-13 psi. I'm running 350 injectors also. Highway mileage is alittle above 20. Mine needed alot of custom chip tuning though.
