What can I do to fix this? Gear swap? Programming? I have a K&N CAI, Jet chip, and aftermarket 22" chrome wheels w/ low pro tires. If gear swap would do it, which one should I get?
I have this same exact issue with my newly purchased (used) 2005 quad cab 1500 "v6 3.7 liter" manual 6 speed tranny. 1st through 5th gear seem super peppy and 5th seems like it could bring me all the way to 120 mph but i hit 3k rpms in 5th at 80 mph so natually you would think "time to swap into 6th" immediately the truck starts losing speed even with the petal to the floor unless I'm behind an 18 wheeler getting zero wind resistance. I'm glad I'm not the only one because I though something was seriously wrong with my truck and I've only had it for two days.
