P0238 code???

So on the way to work this morning I romped on throttle on the freeway and got an SES light. I scaned it and got P0238,and 0000. I don't know what 0000 is but is looks like like P0238 is boost circuit high. I have code tunes I thought I should not get an SES light for boost or is this something different.

That sounds like a MAP sensor issue, not over-boost.

In certain situations DP tunes will still throw the SES light for 30 seconds or so. The "no codes" tunes means that the truck won't defuel during over boost and similar situations.

yeah, you can get an overboost code with a chip/programmer..
best defense is a boost fooler, or simply keeping your foot out of the go-pedal
