Good day, fellow M'ers

I have 2021 X3M (non competition), it is stock, 16,038 mileage, want to start doing some upgrades: Cold intake, ECU tune, downpipe, TCU tune, and last exhaust system, but most interested in First three, then TCU tune.

Have done tuning before on my S5 Audi stage II APR (intake, tune, downpipe, transmission tune and full quad exhaust), would like to do the same for the Bimmer, looking for advise on best tune method and manufacture for each upgrade, I went all APR on Audi on advise. Welcome to same for my X3M.

Thanks everyone
Maurice
