Regarding tunes - I have to admit, I don't understand it at all. Besides that you need a reputable person doing it. What does it improve? Pulling power? Speed? Both are not my issue.
My main issue is pin weight on the horse trailer - 3 horse slant with living quarters. Bought it used, have a large 5th-wheel, and no issue with pin weight there. But I found out, goosnecks are leveled differently...Just got Sumo Springs today (SuperSprings;front and rear) today. Looking into tire upgrade next.
Does anybody know what the rear axle and bearings can actually carry (besides the sticker weight)?
Thanks Sabine
If you can operate a toaster you can install box tuners or programmers. But your not looking for mo power anyway. Yes most will increase power significantly and mileage a little maybe depending on the tune and how you drive.
Your truck has an AAM 11.5" rear diff. Mfg rating is around 9-10klbs. You'll be far over any tire rating unless you step up to 19.5" wheels and load F-H tires before you get near the real axle weight rating.
