Recently purchased the phoenix chip for my 2000 f250 and all I can say is WOW. The tunes are incredible, at least the ones I have tried. Haven't hooked the fifth wheel up to tow yet but the 80dd and the 100perf make driving fun. Accelleration, shifting and just overall drivability are great.EGT's are lower than stock, and Mileage is at or above stock levels as long as the foot stays under control. Thanks for a great product.
