Diesel Dave what gear do you have in that 11.5 aam axle? 3.42? Us gear vendors overdrive? 3.42 gears would be super beneficial to your setup I believe... I have a 2005 dodge 2500, g56, 5.9 cummins, stock injection pump, lift pump, turbo (he351cw), bigger injectors, south bend 3600 dd clutch, aem brute force intake, 4 inch straight pipe, bully dog triple dog (scary Larry tune), edge ez, .... 551 hp- 1074 lb. Ft. At the wheels.. I have considered running the 3.42 gears....
