Diesel Question

I drive a 5.9 2003 Ram 2 wheel drive with a Quadzilla Module--Cold air intake--and a 5 inch Exhaust---those three adds gave me 150HP and a GOB of torque. I can pull my 5th wheel at 90MPH if I want--I don't want though. There is a 2006 Duramax Chevy 4wd that turns 119MPH in 11. at the drags here in Boise--Basically stock with twin turbos and a reprom computor--impressed the hell out of me. Has to run in 4wd or it smokes the tires all the way through the quarter. Still smokes all 4.
