M264 Engine knowledge?

[RacersEdge]

Hi all... anyone with any knowledge of the M264? As far as I am aware it comes in three guises... 194, 255, 295hp. Does anyone have any knowledge of what mechanical differences there are, or is it all in boost pressure, software etc etc. I’m asking cos I bought the C300 coupe (255hp) and my only complaint on the car is that a couple of months in and I’d like more shove. Probably should have bought the C43

Thanks for that. I’ve read a few articles on the engine, but yet to find one that describes how the differences in power output are achieved. Essentially I just wanted to understand what might be involved to get mine up to the 295 variant.
