Anyone tried this? I have a 2017 5.0 F150 and thought about adding a little power to it but mainly wanting a tune to correct some of the factory driveablilty issues, specifically the electronic throttle hesitation when you floor it from a stop and its throttle sensitivity towards downshifting the transmission. I looked into several aftermarket tuners but you have to buy a device, then email tunes back and forth that are not warranty friendly. This Roush kit comes with a cold air kit and a tune voucher. You go to your Ford dealer and they reflash the pcm with the more aggressive Roush tune. So you dont have to buy a handheld tuning device and the Roush tune is warranty friendly. 91 or higher octane is required of course but you can run lower octane with diminished performance. It can be converted back to stock if you want to sell the truck too. This kit lists for about $750 but I bought a new kit on closeout for half that. Thought Id give it a shot but just wondering if anyone else had any experience with it.
