I have been running the JB Stage 1 unit in my car for a few months now. I definitely like the performance it gave my car, but am curious if I can squeeze out some more. I have read about people increasing the boost levels with the USB cable from BMS. My unit has the port to use the USB so I've been debating on getting the cord. My question is what difference has anyone seen doing this? Is it even worth it? I was planning on going to 4.5 or 5. Has anyone measured the gains?

Assuming that you have the newest version, boost cannot be increased on the stage 1

You would need to get the Jb4 stage 2 and run map 5

I'm actually not sure what version of the JB Stage 1 I have, but it does have the interface port for the cable on it.

Here is a link to a thread that discusses the subject.

Your link seems to sum everything up. Get the cable and use the interface they linked to and follow Terry's instructions in that thread. Seems straight forward.
