Let me start by saying your car looks fantastic! And congratulations on all the upgrades and progress that you made. Just quick note on the 340 pack the system is not hard to tune and if everything is running correctly is pretty straightforward. what happens and what has happened over the years in many cases people do not understand the true problem .and they try to tune out the problem , screw with this replace that and fall down a rabbit hole and now they don't know what the hell is going on . I find the system both challenging and rewarding and most of all rare . No need for drastic changes or big system improvements lol. I've been running mine for around 4 years now I've had a couple small hiccups but tuning it is just fun!
