I just got my XCT back from MPH Peninsula, Ohio (authorized Power Commander tuning center) I was pleased with the rideability gains that I got, but was a little disappointed with the H.P. numbers. I started with Ness Big Honkers, Air Filter, and Stage1 reflash. the dyno said 90.47 HP 109.25 TQ. Then with the PCV and with the o2's removed and plugged 91.20 HP 109.49 TQ. The air-fuel ratio was about 13.5 across the spectrum, before it was much leaner down low. I would have liked to seen the stock numbers as a comparison. Am I wrong to be disappointed at spending nearly $800 to get almost no power increase?
