Just introducting myself - picked up an 08 535XI wagon the other week with maintenance records since new.
At the moment she has MHD Stage 1 OTS tune, new NGK iridium one step colder, and new coils ( take a guess at the order... ), and a drop in panel filter. Oh and a new fan + shroud because it exploded the other day.
Trans has XHP Stage 2 + xDelete in Sport setting
Right now a c-PE exhale charge pipe is enroute.
Plans are basic FBO - AR Design DP's, inlets, DCI's, and 100% unsure about intercooler. 5" seems to be enough, but debating at 146k if its worth it to replace the stock turbos with a 15T/17T ( oil pan is leaking so, its one of those while you're in there... ). Probably a flex sensor and E85 w/mix map. Also have M5 brakes en-route. M-Tech/M5 front bumer. Tint. Have an SMG steering wheel en-route for flappy paddle life. Wheels and tires down the road when M5 brakes go on. Of course suspension ( unsure atm between a Bilstein/H&R combo, or coilovers )
I know with the 7.5" there is some cutting of trim happening. Any thoughts?
