I accelerated quickly on a hill to show my brother in law how the EGT/Boost gauges work and the engine revved high (3000+rpm) and the CEL went on. Ran over to Autozone to check, but they didn't have a scanner available.

She's driving fine, but I think I slipped the TC. What code could have been thrown?

 

Better just wait & pull the codes and see what you got. We could guess all night.

 

0234-Overboost, what could have caused that? I thought the VA had a boost fooler.

 

on my truck if im playing with the go pedle atching gages and geanraly just showing my &^( i can throw a over boost code brothers trucks same way he has a diffrent box but normal driven and pullen never throws the code just when play anround with the trottle. i just keep a 75$ code scanner under drivers seat and clear it out (mainly have scanner incase truck acts stupid away from home )
