I have a Genysis and Tech II. The Genysis says that it will do it but it won't for some reason. The Tech II will. If you were near Cincy I would do it for free for you, maybe you can make a post to see if there is someone in your area with a Tech II that will help you.

you can just turn that code off, it is just for misfire detection and wont have any effect on driveability or hp, if you have a cammed engine you probly already have the misfire tables changed or turned off

The guy that tried it did not do all those things. When the rpm reached 4,000 rpm the engine shut off each time.
I'll print this out and bring it with me next time.
Thanks.......

if you arent even using the misfire tables then just turn the code off with whatever tuning software you used to tune the vehicle,, a gm tech 2 cant disable the code,, only tuning software,, hptuners, efilive, tc obd2
