18rwhp from FIPK
20rwhp from Cat back.


This was what some site is telling me , one of our sponsers. 38rwhp from intake and Exhasut on a 4.6L GT. Is this for real? they show the dyno charts and everything.

 

That's probably with the most extreme race tune. Wouldn't be healthy for the motor.

 

+1, those numbers are possible but in order to get there you will have to spend the extra cash and be willing to give up some of your motors life as manystyles said, a race tune like that is def not friendly for a daily driver.
