So I have a 2012 and am from alberta canada, currently running a HS mini maxx street, seems to be re-gening more than usual... 42000 km or 26000 miles all stock besides tuner usually run on performance tune. Has been running great up until recently, lots of regens lately like every 200-300 km, used to be about 800 km between cycles. Thinking my dpf is getting plugged up... strange because I do not drive like an idiot. Might do deletes but wondering what tunes and what suggestions for a quiet exhaust and better mileage. Quiet is a must. Suggestions please.
