maybe whomever had that SF tune can speak up here... my HE pump died so I never got a good AFR reading - mostly in the 9s

Would be interesting to see the AFR using the Kleemann 168 tune with the smaller blower pulley.

Like stated earlier. If your going to tune your car spend the $300 to put a quality wideband in. I switched from the red 550cc injectors to ev14 550cc injectors and AFR's were all over the place when Jeremy did a dyno tune from the previous tune we had on it. Cooling also plays a big role in AFR.

The Dyno chart looks funny to me...HP and Torque curves should cross at 5250 or so based on HP=Torque X RPM / 5252. So there are some scaling or adjustment in that chart? Since the dyno only measures and torque and rpm can be direct from the ignition or approximated by wheel speed pickup etc. maybe that's the discrepancy.
