No need to do anything with the Trinity.

On the LBZ & LMM engine the MAP Sensor is located on the front air intake manifold tube on the front of the engine.

On the LBZ and LMM engines the Fuel Pressure Sensor is located on the back of the fuel rail on the passenger’s side of the engine. The connector is the same as the connector with the orange grommet on our wire harness. You will need to connect to the sensor and the factory connector.

thanks for your support (pics)and quik response if you have got any ideas on how the easiest way to reach FPS I would appreciate them also thanks again JS

It should just be futher back on the fuel rail.

[js]

I shimmed FPV and im still getting low fuel rail pressure and reduced power mode any experience or ideas with this problem ?

[mikel]

confirm the correct torque spec on that valve, I believe it is 100 ft/lbs.

[js]

still cant get the truck to run right. keeps telling me to change f filter and going to reduced engine power codes are po101 p244 and p2453. can the trinity program to run without dpf ?

[js]

been 17 days some kind of response would be nice cmon guys cant keep doin these trucks with out support !

[mikel]

did you check the torque on the fuel relief valve?
are you trying to run the extreme tune with the puck turned all the way up?

[js]

yes torque is 100ft/lbs..and yes extreme w puck down as much as half .what should they be set on ?

[mikel]

the extreme tune adds almost as much power as the fuel system will wupport, so you may be limping it by adding too much and not getting the commanded fuel.

Try a lower tune or try the stock tune and see how the puck works by itself.
