For best results get a custom tune, I myself am satisfied with my plain Ol edge evo, More than satisfied. IM sure the results with a custom tune vs a regular canned tune are way better, but can't be too much better, you can only get so much out of it. To me custom tunes are more for a built vehicle, with more than just an exhaust and intake.so instead of spending more money ima stick with what I have.

 

i have a canned edge evo and i only have it set on transmission shift points. i havent noticed any significant gains. no mpg gains at all.. it does shift a lot better with a load or trailer, i have noticed that. do put it in tow mode, you have to run 89 octane. and performance 91

 

Stock the 5.4 lariats are 16.7-16.9...

With only 3 mods; my custom tune gryphon, borla exhaust, & K&N CIA, I ran 15.6s
