my understanding is that the procede should work just the same, but give shiv or Robert a call to make sure. I would be interested in what they say as well as I'm considering getting a Z4is as well.

Procede, jb4, and Cobb will work. I would reccomend the procede though.

You will definitely be faster with a tune, no question. Why would you think it would be worse?

Since it's an N54 motor, you can go with any of the major tunes -- AA, BMS, COBB, GIAC, Vishnu

There's room for significant improvement as a tune provides the biggest performance gain among all possible mods.

12.7 is very strong for out of the box no tune....

Cobb for sure, and a set of our newly released Z4 downpipes

There are many tuned Z4s running around with JB4s. One just posted dyno results of 386whp/422wtq using a little mix of E85 and the new autotuning map 5.

No additional fuel mods besides just pouring in a mix of E85?

Thanks!

Yep, that's it. Just add in some mix of E85, this Z4 customer used 40%, and the JB4 detects it and handles the rest!
