I hope we get some tuning support soon but I wonder how close to being tapped out this platform is. We know b48s that aren’t internally modified are getting near the output of our cars but I wonder how far it could go. I’m thinking 360hp should be possible but I fear it will become a lag monster since we already have nearly 23lb boost.

The looming issue for x1/2 owners doing mods is the transmission. The x28 trans is only rated to stock torque while the m35i unit has a little wiggle room at 354 ft lb or 480nm.
