Hi everyone! I just joined this forum to seek some advice, I thank you guys in advance I have a 2014 RAM 1500 Tradesman with the V6 Flex Fuel 3.6 Liter Pentastar and I am a little concern about the performance. I did a couple of upgrades to my RAM like 3 months ago: first I installed a Spectre CAI which I really like, I feel my truck has a better throttle response and I love the sound, and then a month later I replaced my 17"s with these 20" OEM black wheels (which changed the look completely) and right after this I feel like my truck is slower, like I'm always hauling something in the highway. I set the cruise control to a certain speed (72-75mph) and looks like is hard for my RAM to maintain the speed; its even worse when Im going on a little uphill I get high rpms trying to maintain the speed set, I rather to just cancel the cruise control and control the revolutions myself. I went to the Dodge RAM dealer and asked them if there is any adjustment that it need to be done after I changed my wheels but they said No, it should be good since it is about the same size and width. Have any of you experienced something like this?, the feel like your RAM is not responding as it suppose to What do you guys recommend me to do or to check? Thanks!
