Hi All, I've searched the forums and the Internet but can't find the answer to my question.
We have a 2021 Ram 2500 4x4 with the 6.4 Hemi. It replaced a 2006 Ram 2500 4x4 with the 5.7. We tow a trailer about 50% of the time, usually with a car or lawnmowers or building materials. We have an 18' open deck trailer, or occasionally tow enclosed trailers or campers we rent.
I am looking for a tuner that will allow me to lower the redline of the engine. That's it. And specifically, I want to enter a number, like 4,500 rpm, or 4,000 rpm.
We are otherwise perfectly happy with the performance, the mileage, etc. I just can't stand the screaming rpm's every time this thing decides to downshift, which is fairly often, even when towing a light trailer. We typically tow from 2,500 pounds to 7,000 pounds. Even with light trailers, the screaming 5,000 rpms on slight grades gets maddening very quickly. I'd prefer to just mash the gas and have the truck hold a taller gear, even if we lose a little speed.
We thought this truck with the 8 speed might be better than our old truck with the 4 speed. But it isn't. The extra gears seem to both be overdrives as far as the driving experience goes.
I bought a tuner for the 2006, but all it let me do was pick between modes like "towing", "performance" , "economy." But none of those affected the rpm's at all. Tuners I find today arent real clear as to what I can adjust.
And to be honest, as far as this issue goes, neither of these trucks were as good as our 1996 1500 4x4 with the 360 gasser. I pulled the kickdown cable all the way out and that truck almost never downshifted. It was great! Transmission lasted for 240k when we sold it.
And FYI - I've had trucks with the Cummins. But the issues with the newer trucks, the emissions issues, and frequent repairs, total cost of ownership, etc. kept us from buying a diesel. We have plenty of friends with farms around here to learn from.
Thanks.
P.S. - Our coping strategy with the 2006 is to tow at 80 mph. This will keep the engine at roughly 3,200 rpm and it won't downshift because it would go over redline. But We'd like to be able to tow at reasonable speeds and have the drivetrain work better for us.
