For most running pump fuels expect power gains of around 100whp over stock. For those who really want to push the factory turbos with a methanol injection kit and higher octane fuel power gains of up to 240whp over stock are possible. The JB4 also supports larger s63tu turbos. We've had customers report as much as 820hp to the wheels using simple Stage1 turbos! Installation is more involved than our Stage1 tuner in that you must run a wire to the cabin for the OBDII CANbus connection and the BCM connects to the wastegate solenoids behind your passenger side intercooler. Connecting the BCM requires draining some of the intercooler coolant and refilling the system after you're complete. For those who simply want a Stage1 with better logging, in dash gauges, boost by gear, code delete, and will be happy with 20psi or less, the BCM is optional. For those wanting to push more than 20psi (maps 2+) the BCM is required. FEATURES For those running a DCT transmission we've found the factory clutch packs are only good for around 640whp before they start slipping. If you are planning for more power than this plan to upgrade to Dodson clutch packs sooner or later.
