Truck gets jumpy at low rpm?

[jason herdahl]

My truck starts to chug and gets really jumpy when I'm drivin threw town or running a low rpm 1000 to 1500 rpm about? My injectors make it do it a little but not nearly as bad as it does now. Anybody have any ideas of wat this could be?

I've been told its the delivery valves in the pump. Mine doesn't do it when it is cold i am leaning more towards valve body modifications that have been done.

It's probably the Adrenaline. It's called surge. I had it real bad and even got worse with the Mach 3's.
So i can't run the Comp tune anymore and just run the 1000 tune.
VP44's don't have DV's.

I would watch your intake temp and see if it clears up more and more when the AIT gets hotter. My truck bucks horrible when the AIT reads less than 90F. I would imagine it is the timing of your Adrenaline. I've fought this problem for three years with my Edge. I'm going to try the potentiometer on the AIT wire someday when I get around to it.

Its not the adrenaline because I just put it in like a week ago and I drove it about a month with no module and it still did it. I'll watch the iat and see if that makes a difference. I'm going to pull out the cross over tubes when it warms up around here a little bit and put new o rings on them and see if there dinged up or something?
