i have a 3" lift and im going to be getting 33's, would i benefit from doing the gotts mod? engine is the 4.6 with a flowmaster, other than that, stock. i dont want to hurt my mileage but i figure if i dont like it i can always go back.

 

well i did the gotts mod today. it was very easy. i notice a little difference but i havent really driven it. ill know tomorrow when i go to school since its about a 30 min freeway ride
