Super easy installation and keeps your warranty.

If you want ease of use and a nice bump in power get the BMS Stage 1. If you are a power user then purchase the JB4. $795 for the ESS vs $449 for the BMS Stage 1 with similar power levels, the BMS is a no brainer.

With the Stage 1 you can also get the USB cable to add an extra pound of boost if you want. They come preset at 3psi over stock..

This thread has been quiet for a while...

I am deciding between jb4 and E-Tronic. Based on the Dyno charts, I would compare E-Tronic to jb4 (Stage 2). Burger's dyno charts I believe is with Ethanol (E30) mix so it reads higher for stock numbers.

From what i gather; E-Tronic is a solid plug and play. JB4 will stay in beta and has some bugs. Installation is more complicated.

I still can't find a single review from an N63 owner on the E-Tronic

On the new stage 1 units you can only decrease the boost. not increase it
