Did Jerry do the tune over your laptop or work with the owner/operator of the dyno? What AFR's are considered good for these motors, 11.3-11.5:1?
I am running a stacked setup with SL55 pump, free flow filter and adjustable regulator set at 66 psi with a tune from Inmotion (Rob's recommendation). I talked to them about a retune and was told within the limits of my system, the ECU would make the necessary adjustments. I have a Zeitronic AFR meter and datalog setup and unless I do anything more, which I doubt, I am OK. I do have NW DCAI and manifolds also. I have a local Chrysler dealer that has a dyno ($81 for 3 pulls) and they actually know something about the Crossfire.
