I'm running the 9lb pulley with impeller upgrade. The tune is pretty conservative at low 11 AFR, the problem is when it gets really hot out you can't push the car. Either that or you need to up the octane to prevent knock during hot conditions.
I'm seeing 9.8 psi with FI test pipes and 2.5" system, might see 11psi if I put the cats back on.
