i just noticed it recently.. but everytime i start boostin..5-6k and then let off.. it smells like heat or something burning.. now its cold outside so i have the heat on but when start to boost i have the heat on OFF.. i dont know if its a burnt ring or something. my friend with a turbo teggy had a smell similar but more noticable and he had a burnt ring and had to pay 5k$ for a built engine... anyone have any ideas... like i said.. i think its just heat from the heater..
