Big power loss
Ok I just put a wicked wheel in this weekend thanks to Nick (weekendwarriorfs32) for his help. Today I hooked up the trailer just to see if EGT's would be lower. It felt like my truck had a lot less power and was working harder to pull my 26 foot travel trailer that at most might be 6000 lbs fully loaded it is 4700 dry. The EGT's seemed to be a litter lower and all my surge is gone. What am I missing? What else can I look at? The truck runs perfect empty. I am starting to thing I might have an issue wth my trailer but it is only two years old please help this is driving me nuts. Just had the wheel berings repacked in November. What else could it be? Oh and i am using the 80T tune.

I just did a run up the freeway 10 -12 miles with it unpluged and it seemed to run with less effort. Then on the freeway back I pluged the trailer back in motor was working harder high boost and rpm to maintain the same speed. Boodt numbers with the wicked wheel and adjusting the wastegate are up to 26. Starting to think maybe one of the braked is binding up. Any other suggestions?

Any chance you tripped the emergency brake switch on the trailer? Say it's tripped, the battery is dead, and then gets charged from the truck once it's connected, so your brakes are being applied. Beyond that, maybe a defective controller?

> If emergency brake was tripped wouldn't the brakes be locked up?
Like the person mentioned, not if it is dead. If the battery is bad, it may not even take a charge. You turn the truck off or disconnect the cable and it falls to 9v or less so the brakes/magnets release.

on a recent trip to Florida, my trailer felt significantly heavier on the way back than it did on the way down, and we didn't buy that much stuff. On a subsequent trip to Florida a few weeks later, the trailer still felt heavier than normal. I have also noticed the RV axles are leaking a decent amount of grease. Probably something I need to have checked out???? And could be a similar issue to OP???

Need to add, when the break-away is pulled 99% of the time you get more than enough to lock the wheels. I go through that all the time on the lot. Transporters drop our trailers sometimes in the middle of the night and leave with the pin. No battery in the circuit or at best totally dead. Forget to check. Hook up 350 PSD and rag the locked wheels through the gravel.
It is really very easy to tell if the magnets are engaged. Clamp-on meter on lead to brakes on street side of trailer. No or almost no amps, no brakes engaged, when hitched.
