Sounds like you need to find another dealer if its not running right when its Stock.

 

Ya i know but they say there are no codes and everything seems ok they check fuel pressure even at wide open throttle well so they say. Wish someone from here was close i would have them drive it. heck maybe i am lossing it heck i am so confused anyone wants to call me 484-764-8878 if they need to ask questions etc.

 

I don't know how you hooked up the power wiring to the Monitor but I would also reccomend coming right off the battery with the hot lead and ground. This makes sure your gettin a good ground. The only drawback is that the box will stay on all the time but they draw very little juice and you can also turn the switch off on the box if it is that big of a problem. My box stays on for days when I don't run the truck for a while and doesn't even touch the battery charge.

Check and fix these grounds and get a fuel pressure guage hooked up and I would bet that between the two things you will find your problem.

 

How's the air filter? Do you have the lift pump on the side of the block or have had the intake update? Fuel filter??? When was the last time you changed it?

 

x2! My guess is fuel filter or air filter.

 

x3, I would also guess fuel or air filter.

 

They have a recall right now on the fuel rail sensor or something like that. It's not letting the rail build preasure like it suppose to, I'll see if I can find it. Here see if this helps. look here

 

X4 on the fuel filter.... when was the last time it was changed?

 

I change my oild and fuel filter like evry 2000 to 3000 miles I am told i am to crazy there but i do since i bought the truck. Its a fresh filter and oil filter and i clean my cold air alot too.

 

X5 on the fuel filter. I changed mine two tank fulls ago and not only gained 4 miles per gallon, but the truck doesn't bog down as much. Just feels like a different truck...

I blame the bio-fuels, but change the filter.
