Hey guys,
Got our hands on a B58 GEN3 for a few days and let me say, it's awesome! I can't wait for this engine to hit the 3 series! They've changed the boost sensors over to digital which makes JB4 tuning even easier, and the built in port injection setup ensures plenty of fuel pressure on tap.
Preliminary dyno numbers attached! Runs were done in 4th gear. 5th gear produced slightly higher power numbers but the pulls were pretty long, since the car is new, didn't want to beat on it *too* much. Around 100whp gained with a JB4 only on ~93 octane! And I think there is a lot more power on tap when we start to get aggressive on the tuning end.
