Between my INMotion tune and the fuel mod that Rob and Woody have come up with I was able to drive the AFR into the 10's with a 181 pulley. The determining factor is boost any time you go above 18.7psi the car starts to lean out. In the end I was able to get a flat AFR of 12.5 in all gears at all rpm's to red line. I know that if I had been able to keep the car till this fall when the air temps dropped I would have hit the 11's In the heat I was running consistant 12.1's and even hit a 12.04. When I started pulling the parts off the motor I found a broken vacumn line so who knows how much that was slowing me down.
