On the N55 you need to supplement with secondary fuel early on to make big power gains especially on ethanol blends. Using a JB4 in tandem with the DME as a secondary control system for port injection (PI) gets it done well. You could also pull it off without a JB4 in the mix but the integration with the DME/data off the canbus won't be as tight. In the case of using a JB in a stacked configuration like this you can also use the JB to raise your boost target further from where the flash is targetting when the conditions (PI flow/fuel pressure/lambda) are all in check.
