So I had dealer do A stage 4 on my ride. used tts-200 cam and tts master tune tuner. dealer talked me out of including 64mm throttle body. said it was too much and would choke out my low end torque. other components were S&S mufflers with power duals. NUMBERS WERE 127 TORQUE AND 118HP. So would the 64mm throttle body improve my hp. numbers without sacrificing my torque? also didnt have decible reducers installed in mufflers. would they also improve performance? thank you for any help. Ido already have the 64mm throttle body ready for install if it will not hurt my torque.
