So I just picked up a 550xi which has the Dinan intake and exhaust setup, and just found out today that it also has the Dinan stage 4 tune. Would I benefit at all from the JB4, and if so, should I be getting this flashed back to stock? The Dinan stage 4, with these mods claims 507/580 crank hp/torque. What do you think I'd see compared to the JB4 on 92 (Oregon) pump? Would love to run a JB, as we previously come from the 335 world.

And before the naysayers come in, I didn't purchase the Dinan stuff, so I let someone else pay the Dinan tax .
