AFR Issues after installing sw catless dps, PLZ HELP
« on: December 28, 2016, 08:54:39 PM »

So just installed sw catless downpipes on the mks, now afrs seem to freeze at wide open throttle at where ever it feels like, typically at 13-14, tryed different tunes, nothing changes, went back to stock and the car runs like garbage ( yes it had the 2 bar in) i cleaned the map sensors, im lost... Has anyone else experienced this or know a fix? bank one seems to be the issue, had a large exhaust leak that i fixed today, still the issue keeps going, please helpp!!!

Not really familiar with the mks. Do the downpipes have bungs for the O2's to thread into? Are your tunes made for catless downpipes?
