ok so, i talked to the people at uprev to try and get a tune or a reflash for my car but it appears that in PR the air temperature and altitude is different, they said that i cant use the maps that they already have, so i would have to get it tuned manually, but the problem is that in PR there arent any uprev dealers and no one sells their product so i cant do anything with uprev. does anyone know of any good emanage or something, another way to get a tune for the car that can adjust timing, a/f and limiter? ive heard from some that work but eventually the ecu sees changes and puts everything back to stock or stock settings
