As you can guess i'm itching for a wideband 02 kit, just been reading about the installation of them ( sad git) and it has been pointed out that where a cat is fitted the sensor should be before the cat. When we went to THOR for the rolling road day they basically shoved their 02 sender up the back of the exhaust a few inches.
You can probably see what i'm getting at here, where people still have cats fitted there is potential for an inaccuracy in the AFR reading, hence , incorrect tuning.
I know its doing it this way is the most practical but im just wondering how big the potential errors could be.
