The Hartge piggyback died and Hartge the Company went broke it seems.
The X3 is not my daily driver and despite its age has a super low 10,000 km on the clock. I bought it new with all the options I wanted and decided its worth keeping and having some more fun. So I’ve embarked a new build:
Michelin Pilot Sport 4S tread
Pure Stage 2 Turbo upgrade
FTP Chargepipe and Boostpipe
Ruff custom upgraded FMIC
Ruff custom cat less downpipe
Ruff custom oil cooler
aFE Magnum Force Stage 2 cold intake
Precision racewerks ignition coils
Colder plugs for tuned engine
Walbro LPFP upgrade (thank you to forum member Hardparker for the advice)
KW DDC Plug and Play Coilovers with EDC BMW X3 F25
MHD Flasher custom tune
Will be interesting to see what I get out of the N55 without internal mods.
December update:
Attached is the baseline dyno and dyno after parts but before tune. Check back in the new year for the next dyno run after the custom MHD tune is loaded.
