Have a 2006 pontiac GTO, has been tuned by previous owner and alot of work done to it, was wondering if the predator sport programmer can display diagnostic codes for check engine lights. also, is there a PDF somewhere for someone like me who has never used one of these before? I see two codes on back of predator, U7191 and 225202.

yea plug up to obd port like your gona tune it and go to diagnostic and then read the codes and it will tell you what you need to kno.. at least my u7194 does.. im almost positive yours can to

yep ^ ^ ^
