Not sure how it is on the newer vehicles, but on my 98 5.9 Grand Cherokee when putting on mods like headers, heads, intake, etc... it took a little bit of time for the computer to learn the new mods. It may level out in a bit.
Tommy, is there a noticable difference in noise in the cabin. I am interested but don't like too much noise in the interior. Also, how is the idle situation now and do you see an improvement in GAS mileage.
just so everyone know my truck is running so ****ty that when me and godfather raced from a roll it was dead even... there WAS a huge difference in power at first. i think i have bad sensors... noise in cab is not much more.
its going in tomorrow so things get worked out before the cam next week.
it is a great mod im just getting the bugs out. i can hardly keep it running at the moment.
