I was going up a mountain Sunday night and my cel came on. Long story short, truck threw a P0234, overboost code. I only saw about 22psi on my gauge when the light came on.

What parameter do I have to change in the tune to keep it from setting this code again? Also the tune has the egr turned off and my truck is non-emission, would that be messing something up? Also truck will throw a hidden maf code but I don't remember the number, and it wont set the cel.

Thanks for the help again. Will this affect anything other than the code tripping? Is there a min/max I should be aware of when changing these paremeters?
I was going to pm you about it, but I thought I would post it that way it is more info for the forum.

I just set my error time to about 100. That way if there is a legitimate problem, it will still tell me about it. Stock for overboost/underboost is 10 seconds on my truck.
