Need Help, 03 5.9CR, no power
 

Hi all, new to forum! Need to recruit some help from the inter web.

For the past few weeks when the truck reaches operating temp it has easily 60% less power or more. While the truck is warming up it has ample power and is noticeable. I have self diagnosed the following along with some info on the truck:

Injector connection tubes, 37ftlbs
New Clutch Fan
New FCA - 500km ago
Lift pump is an OEM replacement and was done 8000km ago
5 new Injectors, 8000km ago
New fuel filter and fresh oil change
Use tcw3 lubricant every fuel up.
Have tried returning bully dog to stock, no help, same symptoms.

As of late, the truck is blowing white smoke on acceleration. There is no difference in throttle feel from 15% to WOT. I empty the fuel filter canister every fuel up, may be overkill.

When I installed the BD boost builder/fooler I had issues, I am wondering if the map sensor is faulty?

When truck is warm, it will stall. Fire right back up and be good for another few minutes. I have noticed the lightest coolant smell after operating, no leaks though.

Any help appreciated, I am thinking CP3 as the truck has 285,000km/ 178,000miles.

Also should mention, no codes are appearing on bully dog, nor the ignition way.

check fuel lines from the tank to the injectors pin holes in the lines tighten all fittings.hopefully you heard the detent ball on the injector tube snap in to place while installing the new injectors so that they are properly alined.I can almost surely say if you are blowing white smoke you are sucking air somewhere.Or bad injector or head gasket issuse.
