Message: [QUOTE="chaselee, post: 1513405, member: 25627"] For a couple days now my truck has had a lack of boost and top end power. Under normal driving circumstances, it drives fine, but as soon as you roll into it to pass or whatnot it jumps to about 18psi and it's like the last half of the pedal is dead. Nothing past 1/2 throttle does anything. I took it to my local shop today and he put it on the laptop and we drove around for a bit doing several full throttle pulls. Mind you most of this is Greek to me, but my understanding is that the tune is asking for a certain psi of oil pressure and it's not getting it. As soon as I stab the throttle, it spikes then slowly falls back off to quite a bit less than the demand it's asking for. I had to leave to head to work, so he told me when I get in it cold in the morning, to jump off into it and see if it's still doing it. Something about with the oil being cold it should run better than with it hot if the hpop is starting to give up the ghost. Does this sound right or make sense to you guys? [/QUOTE]
