Hey guys,

Need a little 2nd Gen Help. Just finished installing an AirDog150 on my Dad's '02. Engine mods are just an Edge Juice with Att. Before the AirDog when standing on it on level 5, the fuel psi would drop as low as 2 psi. Now it will hold a solid 20 psi at idle and not drop below 17 psi WOT.

Now, occasionally when coming off of a hard run, or decelerating and letting off the clutch, ie decelerating and turning into the driveway, the AirDog will drop pressure momentarily to 3 to 4 psi and then pick right back up to 18 to 20 psi. Is this normal or something I should be concerned with.

Now I know the AD150 is recommended for highly modified but up next is studs and a head gasket. Then a new VP44 and sticks and turbo....

While Im here, any recommendations on a turbo for this thing. What size injectors too.

Got a brand new South Bend clutch on it. Hes looking for around 550 to 600 rwhp.

Thanks Yall

(taking the learning curve on Dads truck, cause I want a 2nd gen myself to build.... )

Well after doing some digging I finally found a few post about what it may be.
Right now there is only about 1/4 tank of fuel, seem like it might be sucking a second or so worth or air...

Thanks to all who intended to reply though.

And if anyone wants to chime in on mod suggestions Id appreciate that too.

THat is the issue, the 1/4 problem, mine does the same thing, i just came from a trip where it was pretty flat and i ran it all the way to the "E", I put in 30 gals. But in town taking off or turning it will suck a little air!! Just my .02..
