Fn Tuned - FT77 - Throttle Response Controller - Performance Upgrade

Superb packaging. I’ve installed competitors devices like this to motorcycles so was very familiar to instillation but a little more instructions for the novice would be recommended. Installed in 5 minutes. Unlike others this unit can be adjusted with vehicle in motion. Works flawlessly!! Great investment.

Guys ! This thing could not be better ! Handsdown Take. My. Money. Worth it. . Easy to install , works just as it was described in previous reviews . The delay on the 24 Duramax was just embarrassing ! I mean hit the gas , and find a song you like before this big rig moved ! Not anymore ! Instant response. Very satisfied ! Thank you all at FT. !! So much more enjoyable. !!! 💯🤘🏽

This product gives my truck more get up than a programmer ever has. Truly is worth every dollar.
