I have an 07 F150 with the 5.4L Triton V8. The shifts had a hesitation and the best mileage I got was 16.5 mpg. The performance was less than I wanted from this motor. After installing the Max Energy Programmer, the shifts were firm and there was alot more power on tap. As an added bonus my mileage went up to 18+ mpg. And this was with the regulare fuel setting. I towed my horse trailor up hill with no problem. Great product, easy installation and outstanding performance.
