I'm sorting through the tune and code posts in the coming weeks. For the 50i is the consensus to go BMS or Race chip for best performance?
Thanks . RaceChip is the more popular on the forum lately because of its solid feedback. BMS is still good and will give pretty similar performance to the RaceChip for the 50i (however, nothing will ever be better noted than test driving two F15s side by side and of course a dyno end result). I recommend BMS only because of the ease of install (takes 1-3 minutes literally) since it plugs into the MAF sensors - no disassembling required to get access to them. This will be very useful for you when you are taking your car in for service. You must remove the piggyback. For the RaceChip, because it uses the MAP sensors, it is very tedious to install (takes 20-30 minutes for the experienced user). Just take a look at my OP for the installation differences.
