- 6.4 hemi
So I haven't found any good information on why my 6.4 doesn't hold back while towing. It seems to be something to do with programming. While going down a steep hill especially in 1st gear it acts like the throttle plate opens up. It will do it without a load also. Rev up to 3k or more and then start holding back until it's down to about 2k and then zoom it revs up again. With a load it will never get the rpms back down so you have to use the brake constantly. It's a 2021 tradesman with the 6.4. any advice or help would be appreciated. Dodge told me the egr was opening but I unhooked it and it acts exactly the same witch tells me it's letting air in somewhere else like the throttle.
