855 no boost. No power

I was expecting to get little bit more horse power and runs little stronger but no torque no enough power and killing on fuel

 

Your talking like 2mpg. There is a problem.

 

Yes 100 gallons each tank and I get fuel up every 2 days to do 3 runs at day as far as 45 minutes load and back empty

 

Fuel pressure has to be tested under load. 40 is surely 100 lbs under spec.

 

What color of smoke does it have?

 

When starting is looking withe and in cold days smokes at lot then looks like blue not at lot and get little puff when change gears like black also I noticed with the old turbo it was smoke at lot when use the Jake brake and now don’t seem to be smoke

 

At 2.1 mpg you should have a puddle that follows you, or heavy black smoke. Now you need to keep the RPMs up higher than you have. If they turned that pump up, dont let it come under 1650. Get a working pyro. Now I'm not being smart, but are you sure your odometer is correct? Maybe try a GPS on phone and verify that your calculations are correct? Then address the lack of power for your current situation?

 

I used gps and it’s old truck some gauges don’t work has lot power and low gears it’s 18 speed with 46 rears 411 ratio but at high gears lost power with the old turbo I being getting 20 psi for turbo pressure and now getting 25 to 28 when this gauge starts to move is shaking doesn’t go up straight

 

This gauge all ways shaking when move
