Re: Seen this yet
It was tuned and yes the Powerstroke out pulls it. My GMC was a pile of crap, I always had something going wrong with it also, the last straw was it was starting to lose the tranny at 75k (and I'm pretty easy on my vehicles). It had plenty of power but it didn't handle the loads very well (10k-14k loaded trailers that were weighed) and it liked to run really hot on the EGT's so I always had to back off the throttle on the hills. Now that truck did have a lot more power than my old '00 F-350 Powerstroke did with intake, exhaust, and 75 hp tune.
