Whats Wrong No Smoke

[DMalone]

I need some help guys. My rig is acting strange this is whats up. I dont have the boost i did have, no smoke, loss is fuel mileage, but truck still runs ok just doesnt have the seat of the pants pull like it did have. Could ez be going south, fuel filter,poor fuel, i am stumped. Thanks for all help offered.

First thing to check would be the connections to both the MAP sensor and the data port. Then examine your fuel pressure to check on the health of the lift pump. Thats the two easiet things to start with.

check the hose clamps all along the pressurized part of the intake tract, I haven't had the problem, but it seems the factory clamps tend to come loose...
