[progrezzive1]

i have 2006 mark lt and want to put 24' wheels on the truck do i need to get ant custom tunes once i purchase my gryphon from php or will it compensate by its self to the bigger wheels

Within the Gryphon you can adjust for rolling diameter changes without having to utilize custom tunes. However, I would most certainly look into getting some custom tunes to balance out the performance aspect that will be effected by the larger diameter wheels. Just my $.02...

24 ft wheels will require more than just a custom tune!

Seriously, though, you'll have to ask PHP about using one of their programmers on your truck. I THINK you can do it, but Bill would be the one to tell you.

And yes, with a programmer, you should be able to correct the speedometer, odometer and shift speeds for 24" wheels. What diameter tires are you going to mount on those big feet? Have you lifted the body to allow room for them? If they're too big, you'll need to regear the rear axle (front too if it's a 4x4) or you'll have no power at all.
