I'd still love to see them do a stage 2 and maybe a stage 3 or offer a solid power pack like they do on the 235i which can bring it to the specs below (starting hp/torque us under the M40i as well). If we added something like this package to our M40i's...you'd be looking at 475hp or so and 485-495 torque. That'd be insanity. But they did larger intercooler and bigger turbo on that one and I'm not sure the design of our engine would allow that (especially the intercooler from things I've read).
Max HP Gain 128 @ 6000 RPM
Max Torque Gain 113 @ 6000 RPM
Peak Horsepower 445 @ 6000 RPM
Peak Torque 455 @ 3000 RPM
Factory Rated HP 320 (326 Measured)
Factory Rated Torque 330 (379 Measured)

I'd be thrilled by a stage 1 and definitely by a stage 2 tune. I like the JB4 numbers, but don't want to chance my warranty.
I'll wait on Dinan since they match the factory powertrain. I may have to give them a call next week to see how their testing went with the M40i.
