So I tried to pull the engine code using the cruise control speed up and down buttons and that didnt work, is there a way i can pull the cel without a scanner? Also I finally had a full load, and had to climb a rather large hill on an Interstate with a 70mph speed limit, i ended up in 6L going 30mph up this damn hill while other trucks were flying by me... the most EGT's i am getting is around 775, this doesnt seem like enough heat to me, does that seem low to you guys?

Thanks for the replies fellas. I am new to this truck first and foremost. The most boost I have noticed is about 28psi when i have looked at it. Today was the first time I have even grossed near 80k and it was struggling. There is a CEL i will check what it was for tomorrow I cant remember off the top of my head but I dont think it was for something that would rob power from the truck, I do get an occasional lightning bolt and when that does come on the engine brake will not work i have noticed that. I have been told by some of the other people that have been in this truck that its always been slow, ill update tomorrow with what the code is for... thanks fellas. Also between my runs today and yesterday i calculated about 5.5mpg, probably 50% highway 50% rural areas with stoplights and what not, not much idling past a few min unless I'm loading a machine then im on the road again.

I am driving a 2016 CHU613 with the 445hp MP8 (326k mi) and a 13spd Maxitorque. I am hauling a Ledwell Hydratail trailer that weighs 20k and the truck is just a dog (no pun intended). When I put a 40k lb load on there the truck can barely get out of its own way, and empty I can be next to other trucks that are loaded and they pull away from me. Any idea's on what to look into for why this truck is so slow and feels so under powered? I am not sure on gearing I know it goes 67mph at 1500rpm in high gear. Could it be emissions crap? Something else? Any suggestions or opinions appreciated.
