I just had a 6.7 turbo conversion done on my 02 24v 6sp truck. It has a fleece standalone controller. I wish I never used the truck with out it. Its awesome. super clean job. excellent power gains with adjustable wastegate(that they helped me understand how and when to adjust) and the best benefit of all. the exhaust brake feature that sounds more like a big truck than the other air leaking sounding ones that don't work. IT works awesome I.ve hauled 8 7 ton loads of hay (plusgoosenecktrailer) total wait of 26, and change in the last week and completely love it. Just some info and feed back for you guys that are looking for exhuast brakes and better performance and miles/to/gallon. They have performed this conversion on 89-98 12 valves, 98 1/2-02 24valves, 03-07 common rails. This was all done at Youngs Farm Service and Repair. 717 578 2572 southeastern pa. Wouldn't take my truck any where else! :rockwoot::rockwoot:
