Get a smaller eaton or better yet a procharger. Efficient parts are rarely cheap. The SRT6/c32 superchargers will probably work but I would look at the compressor map to see how efficient it is at the slower speeds you will be driving it at. This car is tunable with FMU and Piggybacks as long as you completely hide the SC or turbo from the ecu, which is easier said than done. It took me quite some time to accomplish that. According to LantanaTX there is a guy at LET that can reprogram the ECU for FI.
