hey whats up guys,

i have an 04 fx4, i have a K&N CAI and true duals with flowmaster super 40's with 35x12.5 pro comp xtreme a/ts, what specific benifits would putting tunes on it be for me with these mods....

thanks for the help greg

 

Your throttle response will be much better, it will bring you back some it not all of the power your losing from the 35's.

All I can is, it is the best mod I ever bought. After the tuning, it feels like a different engine... All the power is there when you need it....

Defenently get tunes, Best Bang for Your Buck

 

And the shifting.. you won't believe the difference in the shifting, at least that's my experience with Troyer's tunes.

 

Depending on the tune, it will add 25 to 30 HP. That is about 15% at the wheels. Best bang for the buck that you will find.
