Hello,
My Gti came with a Superchips remap, I'm looking at adding a decat...does anyone know if the standard superchips map codes out the post-cat lambda?
The reason I ask is my brother has an ED30 with a superchips map and a decat and if he turns his map off his EML comes on, so on his the sensor is clearly coded out. Is this a standard thing? Or will I need to get the map adjusted for the decat?
Thanks
Dom
