New to tuner need help

I have a 2016 Dodge 2500 Laramie with 305/55/20 with the raceme tuner in it

I haul roughly 15k pounds maybe more. I run my tuner on stock VGT and 30hp. Issue I'm having is that i can't keep my speed and in 5th gear my turbo spools very easily. Rpms don't move but turbo is spiking to 35psi. I've tried locking 5th RS run 2k but can't keep my speed.

I’m pulling about the same weight (fifth wheel camper) with a 2010 CC dually 3.73 rear end with a RaceMe Ultra tuner on box tunes. I run plain stock (no added hp) and all other settings on default. I stay locked in fifth gear and run at 60-65 mph. Holds that speed well unless I pull a fairly steep grade. I just roll with it and monitor EGTs. I find that if I slow to 50 mph going up a grade, rpms are too low so I downshift to fourth.

Today we pulled from Del Rio, TX, to Honda, TX. Pretty stiff headwind (20 mph) and some short grades on US-90. On the flats in fifth gear with the headwind, I could easily maintain 60 mph with EGTs around 850-860 degrees. Some of the lesser grades it would slow to 55 mph by the time I reached the top, and EGTs never went over 1000. Never at any point went over 16 pounds of boost.

That being said, I really don’t know what the issue might be but I post this for comparison. Maybe double-check your settings? Like I said, mine is set to stock with everything else (turbo spool, timing, fuel rail settings, etc.) all on default.

I'll give that a try later today when i hook up. I'm just used to my 2012 Cummins with the h&s mini Maxx and i could run 65-70 with no issue and turbo would never spool up like my 2016 does.
