Re: 85 lwb turbo 5.3 build

I know the guys running big boost like over 1000hp dont. Sounds cheaper to me. Not sure about the operating system or what not. Open loop though it kinda weard. Dont cars run better in closed loop cause they use all the motors sensors to figure the fuel and spark tables? I would asume anyone that can tune the motor can turn that on and off? What about mail order tunes? Are they worth the money?
