My current setup is a healthy rb25, gt3071r turbo, stock injectors, stock maf, walbro 255lph pump and s-afc2.

At 10lbs, my a/f is around 11.6 in full boost and drops off to about 11.2 to redline. My question is, is this ratio good or am i hurting my power at such a low boost level.

And as i go up in boost, whats a general rule i should follow when it comes to the boost and a/f ratio reading?
