Ok heres the thing, juice on any level and ez on level 1 the boost is 33-40's. Then juice on any level and ez on 2 the boost tops in the mid 20's and thats floored! Juice on any level and ez on 3 the boost tops at like 31-32, also floored. What could be causing this?

 

anyone????

 

Where and how are you reading the boost? What is your fuel pressure at the CP-3?

 

no pressure gauge yet. i read the boost from a mech gauge with the boost bolt on the intake plate.

 

Both boxes plug into the MAP sensor, right?

Wondering if there is a confict if so?

Possibly fuel pressure dropping to low with the EZ?

Guessing till the really smart people have a chance to read the thread.

 

Bingo. If you have the stock lift pump then the EZ on anything but level 1 will drain the rail because it drops your supply pressure from the lift pump to 0 PSI. I had the same problem when my truck was new.

 

so i need a lift pump, well that a clutch and some traction/ladder bars are the next thing on the list anyway! i was just hoping it wasnt the trubo. Thanks guys
