No your stock ECU can only make so many adjustments, that is why after adding intakes and exhaust most people are running lean because the stock ECU can only adjust its settings so far so by installing a turbo kit then driving it untuned is a horrible thing to do to your motor it might be to lean to rich and you might get some detonation and pop your motor.
