Anyone have info on compatibility with the 21 model and the protune? I have it hooked up and I get no errors, seems quicker, but would love to know if it actually is...and what the gains are. I would assume similar to the 93 oct tune with the jb4. I am running on map 3...not sure if that is what I should be doing, but I found one post saying that was the most power you could run on 93. However, I read another saying the higher the number the higher the power. Would love some info from someone well versed with this piggyback if possible.
