Hey guys, this ecu is run on my 2000 s4 6mt, it will not work on automatic or newer model s4s. Very noticeable power gains over stock. Easily will put you well over 300 crank hp, probably closing in on 400 crank torque. I'm willing to take $300 or a trade for a stock ECU and $100. Thanks.
call at 760-580-9406, my name is Will. Leave a message if I don't catch your call.
or email me at willeldon27@yahoo.com. Local pickup is preferred but I will cover shipping costs if need be.

 

I would also highly recommend running upgraded diverter valves, throttle body boot, and f-hose to make sure you aren't running this tune with any boost leaks.
