My 98 12 valve is low on power the egt only get up to 700 or so and it seams to me that the truck is not getting enough fuel. I have a banks plate full forward and the smoke screw all of the way in and all I can get the truck to do is smoke just a small puff at take off and then it clears right up the waste gate is blocked and I am making around 25 psi of boost this seams low. I changed the fuel filter today and it was dirty and definitely in need of changing. When I was priming the truck with the little plunger on the side of the block I could hear what sounded like compressed air leaking out near the injection pump. I did not see any leaking fuel and was unable to find exactly wear the compressed air leaking noise was coming from help please I need more power.

The noise is normal, just pushing the air threw the pump. 25psi is not bad for an auto. What were your #'s before.

check that your start/stop solenoid is pulling the shut off lever all the way up.

I dont know added gauges at the same time as moding the waste gate my 01 truck makes 40psi ?

I just looked at the passenger side of the head near the injectors and it appears that all of the injectors at the return line are leaking? Could this be the problem?

Shouldn't matter just makes a mess. A lot of the time the TC will soak up any added power and not put enough load on the engine for it to smoke or boost much. It would be great to have a trans like in your 01 in it.

When I got my truck it was a total dog....Mine was the startup solenoid.The adjustment was way out...And the power was reduced by half..For sure check that..
