Didn't notice this reply for some reason.
I don't know you'll get power gains with the asymetric on the 749. Mine gets 100bhp, just, with the Termi and PC3 (or ECU). Wasn't really any difference I don't think between them. The difference comes in the throttle response with the PC3, and (depending on the map), smoothing out the dips in the curve that you end up with because of the compromises in the ECU. For example, manufacturers have to meet noise regs, and the test is done at 5,500 rpm. As a richer fuel/air mixture lowers the exhaust note, you will find a rich spot at 5,500 rpm to help pass that test. You will also find compromises for emmission regs I guess.
Anyway, that is why I am happy with the PC3. As I said, you pays your money and takes your choice. If you want the pukka ECU then fine, if not bothered then PC3 is a good option. I like it.
