NPP exhaust codes after Corsa catback install on C8 NPP valves need to recalibration

[regorih]

Anyone run into these issues on the C8s? After getting an aftermarket catback system installed we receive codes for the NPP valves. The only way to clear them is to have the NPP valves recalibrated by a Chevrolet dealership.

Does anyone know if they can be recalibrated with hp tuners software on a stock ecm or an unlocked ecm??


Thanks

Had to do this on my Camaro w/Stainless Works exhaust. Can't be done with HP Tuners. I got lucky and have a GM tech that lives near by. $50 and he brought his pass through device and laptop home from work.
