Stage 2+ to INS tune
I switched from bm3 stage 2+ to a custom inspection tune the other day...Drove it fine for a few miles to the car shop for inspection. I got out and there was this whirling sound with tons of smoke out the exhaust. I was still confident it would pass the inspection so I waited about 5 minutes for the sound and smoke to go away.
It Passed.
Because of the tune it wouldn't show any CEL. I drove home no issues. Switched back to stage 2+ and no issues.
Has anyone experienced this before? I kind of assumed because of my style of driving with the stage 2+ tune, some excess coolant or oil was somewhere in the system that got burnt off causing the smoke.
