Defuel issue on 06 5.9L manual

**billybob** · September 18th, 2012

Getting random defuels at WOT. Anyone have this problem before? I can post tune to if anyone wants to take a look at it.

What is your rpm limiter set at?

**billybob** · September 19th, 2012

Which limiter? most of them are at 4000

Thanks,

Another log, truck will run strong then suddenly drop commanded fuel and slowly come back up.

I just had the same issue with an 06 5.9 manual, so what did you actually change to cure this? I can post my tune.

try making your boost axis table look something like this.
