Since you have the car, why don't you help us?
- Dyno the car stock
- Add the air filter assembly-your choice(your money)
- Dyno the car (optional)
- Un-bolt the stock exhaust and put it aside to save
- Add new exhaust system-your choice(your money)
- Dyno the car
- Report all findings to us at m3post
Why do we (the world) have to wait to find out about tuning potential until the car arrives in the U.S. as some have suggested here?
I don't understand, Is there is no R&D being done by owners in the countries that are lucky enough to have this car sitting in the stealerships NOW!?
