im having an issure where i am custom tuning my quad adrenaline 4k and ill turn pump max all the stuff up and ill hammer down in third full throttle then shift to fourth full throttle and it goes like a raped ape but then if i let of the throttle and put it in neutral and dont touch the throttle the truck will literally die going down the road this is only if i hammer it and go wot ?? any suggestions

 

your asking to much from the pump and putting air into the injector lines.. VP pumps do not like to be hammered on and then let off all of a sudden it will always kill it

 

what the hell how does air get in

 

air is not getting in your lines unless you have a very low fuel level (E) and are locking up the brakes and then trying to go full fuel.

the way your describing your issue doesn't help... you say you go full fuel in third, grab fourth, then let off the throttle and put it in neutral? What is the point in that? OR, are you grabbing fourth, and the truck starts to die so you have to put it in neutral?

does it do it on other tunes, or only your "maxxed" settings?

 

it does it mainly on my maxed settings and its like lets say i hammer down in third and i pull it out and go neutral and brakes for an upcoming stoplight it will die
