BlackBear, HSW N20 100 shot
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...?
You can try looking in www.tunefiledepot.com
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.
Goto www.tunefiledepot.com, look under stock tunes, look under Chevrolet and GMC...
I didn't see one for 2002 Sierra, but try the 2002 Silvarado (of the same engine size).
