I know everyone here has went with the PCM for less tuner and has nothing but good things to say about it, but I was looking at getting the Granatelli tuner for my truck. Now could anyone of you please tell me what the differents is between the two besides the price. The way I am looking at it right now is. That you can set up the tuner the way you want and if they run a test and reset you PCM you don't have to worry about the lost tune. All you have to do is rest the tuner, right? Now can you rest the PCM tuner if that happens. PLus witch one gives you more power? If you could school me. I would be thankful!!!
