What Kind of Increased Horse Power Can I Expect?

Nikko · 07-09-2008

After I get my car returned from the repair shop I will install the FRPP muffler, the Roush CAI, and the Xcal III tune.

I wanted to know what kind of increase in HP and Torque I should expect. Has anyone used this combination?

I am toying with the idea of replacing the Throttle body but I am not sure what that entails as far as cost and complexity.

up to 20 hp/trq. if you go with a custom tune, u can see up to 25-30 hp/trq along with much better throttle response and acceleration.

Save your money on the throttle body. More hassle than it's worth.
