I have the Whipple on my H2 and it works great. I live in the Caif. desert where the temps are now 110+ and I have never had an overheating problem. Yes you do need to have the PCM programmed and you need to have
all of the torque management programmed out or you will never be happy with the way it runs. I used Ed Wright for the programming and it turned out great. I also had him firm up the shifts, change the shift points, etc. My mpg has picked up a little possibly 1 mpg. The boost will go to 6 lbs. with the optional pulley. This mod has greatly increased the performance and gives it the power that it should have had in the first place!
