Since it's doing the same thing in the 1M, I'd think that it would work. What is the stock boost for the 1M? Something like 9 psi and then 12 with overboost? The JB+ adds up to 4 or 5 psi (at 50% its +2.75 psi) usable all the time. I don't see why it wouldn't work, especially since the JB4 works, unmodified, on a 1M. But I could be wrong.

I think I saw literature with boost close to 12 (0.8 bar) without the overboost and I think with was 1 bar which is 14.5psi.
