check out the link i posted on here....picked up mine brand new with dash pod on ebay for 337....probably best 337 ive spent on a vehicle ever!
you have to keep your foot out of it to improve your mpg... lol. Try a cruise on the hwy and keep it at 65 and check your instant mpg.
lol i think thats my biggest prob....all i wanna do is haul ass wherever i go! i did put it back on level 2 tho...lol level three was gonna get me pulled over or killed...
you should man, i have had mine on for four days now and i am totally happy with it, it's a whole new truck now.
