i have a 06 lariat 5.4 and the performance increased dramatically with the gryphon. i literally knocked 2 seconds off my 0-60 (canned level 3). i could barely spin the tires before i got the programmer. i've only done a handful of 0-60 runs but i'm averaging 7.70. i was in the mid 9's b4 getting the gryphon. i'm looking forward to getting my custom tune.
i should also say that my test runs were done on private property as safely as possible. i wont be doing too much more fooling around because 20 inch tires are expensive.
should also add that my truck is stone stock except for true dual exhaust and the gryphon.
