PowerCommander Tuning
Recently installed a PCIII USB on my 96 ultra with FI. I already had the Stage 1 kit with Bub slip ons but added an Andrews EV13 cam for more midrange power. Had it dyno tuned at my local HD shop. It runs great, however, the gas mileage has gone done from about 45mpg to 35-37mpg which is more than I expected. On the dyno sheet it shows the fuel ratio to be about 14:1 throughout the rpm range. That sounds a little rich to me. Anyone have any info. I thought it should be about 16:1. Prior to dyno tuningthe ratio was off the chart at 18:1 in the 2500 to 3500 rpm range then gradually sloped down to15:1 at 5000 rpm.

RE: PowerCommander Tuning
With the EV-13 installed and the PowerCommander programed with a factory preset map the dyno showed 61.5 HP and 77.5 Torque. The final tune shows 65.5 HP and 80.2 Torque. That is fairly significant over stock which according to HD is about 65 Torque and 50 HP.
