I recently added a boost fooler on top of my Superchips programmer. I'm noticing that when I accelerate quickly there is a slight hesitation and drop in rpms, then it comes back and continues to boost and accelerate. I'm thinking that with these two mods stacked I'm not getting enough fuel to the system now causing a slight lag until the fuel pressure catches back up. Have I reached the point where I need a fuel mod such as a dual fuel feed line, or bigger injector nozzles? Any suggestions or similar issues? Let me know what you guys think..i'd appreciate it.

 

FASS or AirDog pump. Should cure you... If that's what the issue is.

 

thanx for the reply dirty dodge...does it sound like I'm diagnosing the problem right? boost and rpms go up...then hesitation with slight rpm drop...then rpms start climbing again after a half second. Seems like a fuel shortage to me...sound right? remember, i only started seeing this issue once i had the boost fooler stacked with the SC tuner. and would a dual feed fuel line be enough? I'm just looking for a little more fuel flow without a load of labor charges for a new lift pump or something to complicated.

 

I'd start with checking the pressures behind the lift pump and behind the injector pump, if everything checks out, then I'd disconnect the fooler and the superchip. If it goes back to normal, then you have your culprit. Try them separate from each other. Maybe that'll help. And I wouldn't put a dual fuel line on. It's still gonna have the same pressure at the rail either way, unless you add a higher flowing lift pump. Better off just getting a FASS or an AirDog. I intend to soon too simply because it's going to help out a ton.
