Your COS5 tune is based on 12212156...Quote:

You could try full flashing back to your base OS 12212156 and see what happens.
Is there anywhere I can get a stock tune to compare them because I didn't tune it someone else did
Can you get your stock tune from your tuner...?Quote:

I would go back to the stock tune (12212156)... you should be able to find it at www.tunefiledepot.com

No worries... if the truck is physically unmodified, then you should be able to pass on the stock tune.
Your stock tune might not be 12212156... just look for the one of the 2002 Silvarado/Sierra tunes that matches your engine size.
You know where I might can find 1?Quote:

I didn't see one for 2002 Sierra, but try the 2002 Silvarado (of the same engine size).

I'm starting to think that maybe it didn't come with EGR.
