This does not mean that one could not push these levels beyond these limits to achieve bigger numbers on the N54 as we have seen some tuners do we just dont recommend or practice it.
We tuned the Z4 with these limits in mind like we do all of our projects keeping safety, reliability and performance in mind. We feel that we have achieved a nice balance and the most power we can without risk of issues or long term damage to the motor or transmission.

Ok, got it. Reliability for street cars is a big deal so it is important that you are making sure you don't exceed the factory specs (too much
).
Yeah, you guys did a great job milking those increases from the stock hardware.
