I have a 2005 Ford F150 with a 77 series k&n intake and mbrp catback dual exhaust and am running stock 275. i am wondering how good the gyhron is compared to the evolution . i have the evolution but just want to make sure it is worth it. :shrug:

Because of your aftermarket CAI you should get a gryphon with custom tunes, they help prevent the truck from running lean. If you had stock everything you wouldn't notice much, if any, difference between the canned tunes in each box.
Hope that helps :)
