Cruise Control more aggravating then helpful
Alright guys I have googled a bunch and I couldnt find any articles relating to this particular problem. Well im not even sure if its a problem but doesnt seem like how its should operate. First off I have a 2008 6.4 job 3 with an egr delete, edge race tuner(running level 2 tow tune for now bout to upgrade to a spartan), dpf delete and cold air intake. Now when ever I turn on cruise control and hit any kind of grade especially while towing the transmission drops down a gear or two depending on the grade i guess and load it senses and then revs to the roof and maxes out the boost. This whole process is very abrubt and aggressive. Egts start off stable but then start to climb rather quickly. This is usually when I turn off cruise and control the throttle manually. Now if I hit a grade while controlling the throttle myself I barely have to lean on the skinny pedal just a tad more and she chugs right on up the hill without missing a beat or loosing a mph. So is this kind of thing normal with these trucks or this an actual problem.
