I'm trying to decide if I should get another tune or just pick up my own. It would be a good thing to have and I wouldn't have to keep paying for retunes everytime I mod...BUT I also know that the software takes quite a bit of time to learn, and if you don't know what you're doing you can **** up the tune pretty easily. So what do youguys think, should I get my car retuned by someone who knows what they're doing or should I try to learn this myself? And if I do...DHP Powertuner or HPT?
