Do you have a fuel pressure gauge?

How much fuel pressure do you have? Is you lift pump even working?

(10 PSI Minimum Pressure required)

You might check for error codes...

If it is an auto and is shifting then they probably have it defueling then.

Unplug the box and replace the stock plugs, the wire tap can stay on. Like said above check for codes. How many miles, you may be looking at getting a new I/P.

When it defuels does the power loss stay constant or does the truck shift and go on like normal? There is a place in the menu on your moniter the allows you to decide how hard the truck fuels at the shift points. Maybe this is your problem.

2000 CTD, HOT Juice w/Attitude, Smarty, Mach 2 injectors (105 HP), 4" exhaust, BHAF, SB Clutch, FASS 150 ARP 12mm studs, stage 3 snow kit.

2008 f350/96 cummins in the works.
