Hey guys,
As I was warned, I have the check engine light after installing my aftermarket cats.
I've been told its because the O2 sensors (I believe the post cat ones) are picking up more emissions due to the new cats (apparently common after replacing with hi flows)
I know a dyno tune is a fix, but I have 2 questions:
1. Is there an easier way to stop this rather than a dyno tune? I've seen the spark plug defouler trick used on some euro cars, could this work/will it fit for a WL?
2. If a dyno tune is a must, how much am I looking at for simply reprogramming the ECU to not whinge about emissions?
Please no 'why hi flows/extractors/tune in a V6' or anything related to V6 bashing because it really does not help.
Thanks guys
