So I was at work today fixing my maf problem and I decided to see if there were any updates for the pcm and gm has two new update for the stage kits one for a code p0171 and a p0507. so if anyone is having a problem with these codes there is an update for it.

 

Yes but from what we know so far you will lose your 7K red line and be back to stock rev limiter.

But this is still not 100% shure.

later

 

wow that really sucks.

 

This isn't true. Go back and reread the thread. The was a problem with the new way GM is administering the flash so the people without the 7000 rpm redline wasn't reflashed with the Stage reflash

 

i have the stage 1 and reflashed my car today and still have the 7000 rpm redline. the update is for the stage 1 and stage two with this problem.

any news on whether the updates include any performance gains? or just a fix for those codes?

 

if your getting one of those codes your likely not getting the performance intended though the actual updates don't add performance it can be considered a performance gain if in fact there was an issue previously. I have noticed better overall response after getting my car reflashed to the latest updates yesterday
