JB3 pinout is under $400 and it's not much harder to install than the true PnP harness version of the JB3 (or procede I'd guess).

I started with the JB3 pinout which is easy to install but because the fuel pumps on the N54 seem to have as little as a 5k mi die&swap interval, you're better off picking a tune that's easy to remove (before service). The pinout isn't bad but I found it tends to scratch up the wires and may leave telltale signs you've played with the DME/ECU where the true PnP version would not.

Both will wake up your car an unbelievable amount.
