Its just a big cam... lots of torque and HP
but drivability suffers a little. I was told it CAN be tuned out by my tuner wasnt able to do it. I have a friend running almost identical specs on his cam and said he has no surging... but his is an A4 with a big converter and 550shot of nitrous. on a stalled A4 it wouldn't be as noticeable..sounds like yours can probably be tuned a lil better
someone that tracks their car would be very happy with it. But mine is a streetcar more than anything else, Like to take long drives occasionally so I decided I would go smaller... I can send you over a couple tune files u can use as a referance to get ur idle sorted out. they are .tun files though
(efi live) but u can download their software to view the calibrations
