I have no problem except at high rpm`s usually over 50 mph plus with my foot really in it. Engine cuts in and out very quickly until I let off on the gas pedal then its fine. I never noticed it until I installed a superchip on level 3 the 70 horsepower level. What is doing this?? After I added the intake and intake manifold it actually doesn`t do it as much, still does it maybe once a week. I might be just going crazy but I swear it has got better though, or maybe I am just not layin` the pedal to the floor anymore dont know. I know yesterday was getting on the off ramp and hammered it accelerated fine with no apparent stalling whatsoever. Went from 30 to 70 in a few sec. with smooth acceleration.

 

does it completely cut out, or is it more of a surge?

A lot of people seem to have issues with high RPM surging when they chip their trucks, most of the companies have updated maps that get rid of it, I'd email superchips and see what they have to say.

Additionally I've heard people saying that a injector that isn't flowing correctly will cause symptoms like that as well, I'm not sure how much it would cost but you might want to have those flow tested to make sure they are all working correctly.

 

Surges constantly in and out till you let off on the pedal

 

I'm sure someone else will chime in that's more knowledgeable on the subject than I, but in the mean time I would definitely shoot superchips an email to see if it's something they are aware of and have a map that will tune around it.

I know for sure the guys testing the adrenaline unit out were having lots of surging issues and qzilla just keep releasing maps that would get rid of it, I wouldn't be surprised if it was the same situation here.

 

All that stuff you have on your truck and i don't see gauges on it?
What's your fuel pressure? Could be running out of fuel and starving the VP44.
