I was searching RPO codes this monring and ran across another decoder after I used the tgo decoder, thought some of you might be interested it seems to have all of chevy's camaro and all of Pontiac's Firebird codes as well anyway hope it helps I found some of the codes that the tgo decoder didnt have.

 

Thanks! I was able to get ALL of my RPO's from that!

 

I know this is old ..but thank you for posting this, It took a bit for me too unlock for printing but this list is awesome for RPO's
