Truck has been surging any solutions.
So I had some surging issues. What i mean by surging is that the truck boost low around one psi than goes to 5 on highway driving while in cruise is activated. I went on a 800 mile round trip this weekend and it did this horrible, but it only started doining it around the 300 mile mark / 5 hours of driving it is the worst it has ever done it i was traveling 75mph and it would boost for 8 than jump to 15psi while on flat ground. I thought that maybe it was since i had the cruise on but i would do it while my foot was on the gas and i was keeping it at a constant speed. It killed my mileage really bad. I only got 16 or 17 when i should of got 19-20. On the way back it did the same thing around the same time about 100 miles from home i was going 62 mph and it would boost form around 2 or 3 to 7 psi.. I know it is not the quadzilla tune i have because i just changed it because i thought that was the problem.. Has any other people had this problem??? Does anyone know why it is doing it??
Thanks Brad

Had a thought on this what about intercooler leaks? I just got back from the hardware store and fitted me up some plugs for the boots on the intercooler one end with a valve stem for charging with air and the other capped off and press it up to about 20psi and check for leaks. the pvc fitting cost about $6 so its worth a try and fixin air leaks in the intercooler can't hurt either ill give it a shot see what happens will let you know when i get it done. will try to post pics of my set up too

Well i am not sure how my fuel pressure is... I have a glowshift fuel pressure gauge and am tired of buying sending units for it. And once again it went out so i am saving up for a mechanical gauge.I am pretty sure that i have good fuel pressure. I also just replace the fuel filter on it.I have the Recon monitor with my Adr. I always run on 2 since i feel it get the best fuel economy but it did the same thing when i put it on tune 00... The only thing i did to the truck was replace the exhaust manifold, but it did it prior to this as well. Also it only did it when i was almost there.. Could it be a heat issue??? IDk..
