I'm the proud owner of this car. I just returned from Rapid and the motor is sweet. Indeed the motor cruises real nice. I'm going to put a few more miles on it before I hammer it.
Mike is great person to work with and he knows his stuff. He answered all my questions, no matter how many times I asked.
With a 200 rwhp increase, I need to learn how to drive this thing.
Thanks Mike

nice numbers, this is through a m6 or a4? Those are some nice numbers witha 408ci, compared to others ive seen, could you say that the AFR heads are the reason for the power numbers?
