Great thread.
Any plans to strap the X5 on a dyno to see what its putting down to the wheels? I had the JB stage 2 on my previous F10 535xi N55 and guys with downpipe, JB S2 were barely cracking 300whp which is a big disappointment. Most were in the 280whp range which is VERY low for a JB stage 2 car.
Curious to see how the JB does on the F15 (i would expect similar results)
