Was able to strap it down with the BCM installed and I'm very impressed with the factory turbo performance. Made a drama free 570whp on E35 fuel. Still no meth, no exhaust mods, etc.

The only drawback with the BCM is you need to cut an OEM wire to install it. It will likely remain an optional part of the n63tu JB4 system, but if you're looking for big gains, it made a huge difference. So much so that we are maxing out the factory 2.5bar TMAP sensors. Fortunately the JB4 can run 3.5bar TMAP sensors. We'll be swapping over soon.
