Thanks for your response. Approximately how much did this cost? How many miles have you put on truck since you  upgraded it? That fuel savings should help pay for the upgrade.

I have a 2005 CV 713 Granite with AI 460 and 18 speed in a quad axle dump truck. Weight is around 73300 lb. Inframe 40000 miles ago. Running in very hilly country. Does anyone have experience with the Steinbauer module, does it work as advertised, will it put too much stress on the engine?

I have a 2005 Granite with AI 460 engine. How much oil does it need at regular oil change? Also has 18 speed trans, 433 gears and 22.5 tires. I run 65mph a lot, engines turning  a little over 1800 rpm. Loaded, the truck weighs around 73500 lbs. Would putting 24.5 wheels with 11r 24.5 tires help or hurt? Seems to me its geared a bit low.

Thanks
