Hello All,


I have a 2000 7.3 and I have a hypertech Max Energy Programmer set to stage 3 in my truck right now (100 HP). I noticed last night when I was going up hill and had my foot to the floor the truck would hesitate for a minute and then lag before it was would catch up to itself. I did it again on some flat ground and noticed when it did do that my boost gauge would get to 20 and then fall to Zero. If I start out and gradually get to the floor without punching it the truck drive fine. Any ideas and how to fix it?

 

A boost leak can do this. You can search for "boost leak detector" on this forum.

 

Your throttle input is "fly by wire", which means you are telling the computer you want to go faster, and the computer is accelerating the engine. If I stomp the pedal the truck doesn't impress, but if I gradually give her skinny pedal input I can get up and go pretty good.


The computer is not seeing something it needs to see in order to accelerate at the rate you are asking.
