yeah my cars work so i dont need to prove much with the chip reset i should be able to push it right over 150rwkw maybe as far as 160 but who knows then i want to reset the cam timing to bring the power down from the 5-6000rpm to make more useable torque

A while ago, someone on Fordmods has posted before and after dynoplots when upsizing his throttle body. It showed basically no difference at all (at WOT) below 5000rpm, but power does continue climbing above that where the stock throttle body starts to limit flow and power. So it gives a higher peak HP and at a higher RPM, but no difference in peak torque. You would typically get less throttle response at part throttle because of the bigger throttle bore and resulting lower velocity.

Well said.

Although I do have larger throttle body installed, and it's all good as far as I am concerned. No worries either way though. For $100 it's worth doing IMO.
