My '10 m8 bd pg is running no more than a 1050 degrees and my octn light comes on and off. I mixed 4 gal av gas hoping it would fix it, it didn't. Dealer set boost to 6# but I am getting about 8#. It cuts out when I grab a hand full of throttle but then takes off like it should leaving me in the snow 20 ft back with bruised ribs. Any ideas?
