Item is called NM Engineering F56 PowerModule.

Their internal part number is NM.648846

Here is a direct link to the company page about it:

I did the upgrade about a month ago and find the extra power very welcome and very noticeable without having any negative effect on overall drivability. Response in almost every gear is now much more aggressive when you floor it, yet almost the same when driving slower in day to day traffic. Very good investment!

The butt dyno states that it seems to add some boost in MID and ECO modes as well. Fuel efficiency suffers, but not significantly enough to matter and the PRO Exhaust sounds like a motorized symphony.

Overall, I am finding the JCW gas mileage not very good, averaging 7.3 km/l before the NM Engineering upgrade and 6.9-7.0km/l now (which is a bit disappointing compared to the 7.3km/l turned in by the 3.2 litre straight 6 turbo in the BMW M135i I traded in for the JCW). That said, I don't buy sports cars for their gas mileage and definitely have been pushing the JCW almost every day since I finished the break-in period

Are you in uk on our grade fuels or on U.S grades? Thanks for the advice?

I'm not sure about that. Though from the US, I have been based in Japan for the past 3 decades and don't know much about US fuel grades. I do know that the NM Power Module needs to tun on the "low" setting in Japan, but this still is more than enough for me as that "seat of the pants" difference is definitely present...

The N55 in the M135i is a 3.0l engine

The N55 in the M135i is a 3.0l engine

For some reason I thought I saw it advertised as a 3.2 liter (though "135" seems like they are trying to make us think it is a 3.5 liter). Nonetheless, 320hp out of a 3 liter engine with manufacturer claims of 0-100kph in 4.9 and most car magazine road tests showing more like 4.5-4.7 means that however many liters the engine is, BMW did a **** good job of making this a helluva smile-inducing drive...
