MR2driver....15 HP to the wheels in an N/A ?? wow...for just upgrading the ignition system....i woulda never thought....but for $400 i think id rather invest in an ECU upgrade to get rid of my rev-limiter. By the way i hear that some people can burn your stock computer chip to give you better gas mileage and to bump up your rev-limiter....anyone know more about this ? thanks.
