Do not put peal'n'seal in your car...! Buy the real thing, not all are created equal. I have Dynamat Xtreme in my doors and it got rid of the twang of the sheet metal. I've always had high end audio systems in my cars and have gotten use to installing it in any vehicle I own regardless of price.
I dragy tested mine before and after literally within hours on the same exact stretch of road in the exact same manner and the averages were 15.3 @ 90mph stock, did the same after a tune it went 14.2 @ 97.5mph.
I run the AWE on my truck its a nice setup, sounded good on the Raptor my brother had so I tried it out and so far its enjoyable and even the lady doesn't notice it.
I took mine out without do anything but removing the bolts and applying a little penetrant to make it easier to wiggle them out. The rears however need to be cut unless you want to take half the truck apart. I plasma cut the rears out of mine. If I sell the truck they can have the ReadyLift bars.
Sounds like a rip off lol, I did the Fox 2.5 coilovers with reservoirs and rear piggyback shocks in under 2hrs in my driveway. The dealer aligned it with my Ford points.
The front is terrible it’s like riding in a 1990 Cadillac with worn out shocks it never settles it’s constantly wallowing up and down and feels sketchy on twisty roads, the rear is stiff enough that it feels as if the rear axle is leaving the ground over joints in bridges. The Fox 2.5 DSC fixes...
I use the Ford Performance tune to adjust for my 33.6" tire, without adjusting the trans shifts were timed terribly lugging constantly and the speedo was off 4.5mph at 65.
It says nothing about use of larger tires, only wheel size. If you're that hell bent on a warranty don't mod it. My dealer is 100% okay with it, they even aligned it and mounted and balanced the wheels and tires with 0 issues.
It's been answered before, yes you can run larger than what the tuner specifies and it will correct... It's input by revs per mile which tire manufactures list. I run a 295/70r17 and it corrects for them 33.6" and even bigger upon my testing.
