Default 4:56 gears and Detroit Trutrac installed!


So i just got my truck back the other day from Gearworks in Clearwater FL. I had them install 4:56 gears and a Trutrac LSD. I am just finishing up the breakin cycle. I have been running 325/65/18 Terra Grapplers but just put a new set of 35/12.5/18 Cooper STT's

The traction and acceleration is mind blowing, however, my city milage is reading 10-11.5 significanly lower from wheni had the crap 3:21's

My GPS is reading speed just about spot on and I cna't get a solid answer if I need to get the computer flased to relfect the gearing change to correct shift points.

The dealer quoted 69.00 for the gear adjustment and 69 for the tire size correction that I never bothered with. Please advise...
