I'm not sure on the tuner yet. I don't like how you have to buy credits and the tuner with HP. Then again maybe HP does a better job than somwrhing like a Diablo? I am going to learn to do it myself. I already downloaded the stock transmission shift values and some modified ones people have done to try those out when I can afford to buy one. I like to learn to do things myself. Saves money and is ultimately more satisfying in the end.
Agree 100% with learning to do it yourself! I haven’t had the time to delve into it myself at all. I bought a tune from
@BlackBearPerf for my ‘03, and am very happy with it. As far as I’m concerned, there’s no comparison between an off the shelf tuner, like a Diablo, and a tune specifically designed for your vehicle, whether that’s an HP Tuner, or BBP, etc.. there’s a pretty steep learning curve for doing things yourself, so buckle up!
