Xeno brought his 2021 BMW M3 Competition into TPG Tuning looking to wake it up and add some more power!
We started with an ECU unlock, then added a better-flowing exhaust system and MST intake setup to help the S58 breathe.
From there, we strapped it down on the dyno and dialed everything in with a custom 93-octane tune using MHD software, then finished things off with an xHP transmission flash.
A simple combination that completely changes the attitude of the G80 and makes an already impressive M3 even more fun to drive!
