You don't have to waste a pos. with the whisper tune. You can combine it with another tune.... I have the whisper tune on the 40Tow tune.
Depends on what you're application is. If you tow regularly, get yourself some tow tunes. I know for daily driving most people like the 80 or 120n tune. And if you're wanting to smoke some ricers (in more than one way) get the 140hp.
