tuned dosnt mean that the tires roll and the engine dosnt blow Im guessing it just dumps fual rediculously at idle and low speeds, which means untuned and running poorly. I highly doubt you had a modded out engine in your 420, i have a 420 in my driveway and can tell you its worthless. Dont get so fiesty in here, mitsustlye is here to help you from experience not just pulling it out their ass
