Personally for the money I'd find someone to build a tune for his truck...not just some generic voltage "controller" A true "tune" will address many aspects of fuel,ignition and trans controls, not just throttle inputs. I bought a SCT/Bullydog tuner and a custom tune from a well known tuner for my '13 F150/5.0 Coyote/6spd auto truck......believe me it makes a BIG difference! Easily swapped back to the stock tune if needed. Right around $500
