Hey everyone. I have a 2007 ram 1500 q.c. 4x4 5.7 hemi. I have a cat back flowmaster and homemade cai and diablo preditor tuner. Any ways I am having a bit of an issue with the truck not seeming like its shifting just right..The rmps go to about 2000 to 2500 when maintaining steady pressure on pedal (65 mph) if I take all pressure off pedal for just a second rpms drop back to 1600 - 1800 rpms. Noticed it is doing now at about 40 mph also. Could this be a t.b. or trans seilinoid issue? Any help? Thanks.
