I got your back xhonda, I am on the same boat as you. I got a pre-tuned PCM and a aeroforce scan gauge to check for knock and other parameters but everyone I know says that a tune will help me optimize the rockers. The problem is that I dont know ANYTHING about tuning. I am not very car savy either. I understand that its good to take the time out and learn but the problem w/ that is if you dont know what you are doing then how do you know its right? Obviously if you have hours to devote to tuning then go for it. With all of this being said I will still end up just getting HP Tuners and learning what the hell is going on w/ my car. Does anyone know if HP Tuners is better than Power Tuner? What do you all recommend.
