I thought my ears were burning
Ok, the gains were not only from superchipping the 172, it came from the freeer flowing k-tec exhaust, Pipercross Viper cold air induction kit and then having the ECU mapping setup to compliment these mods specifically by doing quite a few runs on the Power Engineering rolling road, tweeking the map each time.
My RR results are available if you do a bit of searching around here somewhere, and theyre some sort of proof of the power output at that point in time.
In my mind it was well worth it, a definite improvment in pickup, and the max bhp actually came a bit lower down the rev range to <A target=_blank href= "mailto:184@6091rpm">184bhp@6091rpm, with a nice torque pickup too.
