Is anyone running erics "street power tune" if so what do you think? worth it? smoke? fast?
On average with all things equal the Higher horsepower tune will deliever better MPG because of the way it is utilizing all the fuel. Better atomization, less pedal required to get up to speed, etc.Care to elaborate more?
Also if your driving "normal" trying to get good mpg's is it better or worse for your motor to be on extreme street or something else considering the timing difference and what not?
