So i think there might be something wrong with my truck..Its a 1998.5. Stock idle i have 17psi. stock wide open throttle i have 11. pos 1 i have around 9 pos 2 i have 7 pos 3 i have 4 pos 4 i have 2 and 5-10 i have none at wide open throttle. Is this suppose to happen?? The lift pump and vp was just replaced last year.

 

Are using the Adrenaline to monitor fuel pressure or a mech gauge? Is you lift pump a stock carter pump? If your running a stock carter its not able to keep up with the fuel demands of the adrenaline and I would recommend an aftermarket pump such as a FASS or Airdog. If your using the Adrenaline to monitor fuel pressure is it the updated kit? Also what else are you running? Stock injectors?

Well i just bought the truck..It has stock injectors that were just replaced. Mechanical gauge to measure. I think that it might be the stock one i'm not sure he said the lift pump was upgraded.He said he also replace the stock vp with a 235 hp bosh.. The guy said it has some special type of waste gate.

By chance does anyone know what setting is the best for fuel economy??

 

You need a lift pump, best setting i found was1 or 2, 1 is just timing added.

 

Get the AirDog, I know I did while it was on sale!

 

Yep I'd say you need to upgrade! I can pull my Airtex down to about 3 PSI if I'm romping on it hard. Its no surprise the stock one is even worse.

 

get an air dog right away...in the meantime, turn the adr off or run it on its lowest level...the vp wont last long at all if you keep sucking it dry...

 

Ok guys will do i don't want to spent 2 grand on a pump..Are they pretty easy to install??

Ok guys i think i am going to have to do that. Do you think i need the 100 or 150??

 

I had the air dog 150 on mine
it is pretty easy to install
since you are not sure on the injectors you have i would go 150 and who knows after ya finish school ya may want to do more upgrades for more power

 

go big and don't look back
