Gas milage will suffer correct? due to driving fast or it makes the engine suck up more gas?
Sorry I'm a little uneducated these things but need to learn...
The new version deletes codes automatically. Gas mileage doesnt suffer at all, but your ability to drive slow does. Its a completely different animal with 85 more HP. If you took it off before you took the car in for a service I dont know how they could prove you have one but most service advisors are cool about it just ask them before you bring the car in.
