We were not logging KR, but I also asked Bill Hahn about the same thing and he said it was normal. As far as his being lower numbers for Stage IV, I think he does not have the high boost option on his stage IV (valvetrain upgrades like mine has). Without them, you really can't push the boost past 15psi. My car is pushing about 375whp with the valvetrain upgrades on 100 octane and 18psi of boost.

Bill Hahn thought it was a good idea to run 14:1 A/F on the tune during peak torque?

Uhh...
