Congrats! Welcome to the club. The torque is what is so amazing - and also what can be handful coming out of lower speed corners in 2nd gear. So much fun though.
These were the wiring changes I made to run a DME 7.8 engine management computer from a 2003 Carrera 3.6L. Mine was a race car so I did not hook up the EVAP canister and I removed the catalytic converters and associated SAI system.
