BMW Performance is now offering an upgrade to turbo-charged BMW owners eager to get more power out of their Bimmers without exposing themselves to the potentially dodgy work of an after-market tuner (well, perhaps some of the small ‘fly-by-nighters’).
The twin-turbo six-cylinder N54 engine found in the 335i and 135i can now get a 15kW (20hp) power and 50Nm (36lb-ft) torque boost from the BMW Performance Power Kit, courtesy of new software and hardware upgrades.
Maintaining the BMW warranty, the kit is made up of ECU tweaking and additional water cooling for the turbo system.
The effect on performance is marginal, with standstill launches expected to be around 0.2 seconds faster, and passing (acceleration when overtaking) 0.5 seconds quicker than previously. As there’s no pricing information available yet, it’s tough to say if the kit is worth it, but we’ll keep you updated as more information is made available.

I wonder how much it will cost for an extra 15kw and 50nm which to be honest out of a turbo car really isnt that much!
I suppose it comes with a factory backed warranty which is nice. I wonder if there’s certification too which allows second-hand buyers to determine which cars have had the treatment.
The 335i already has 400Nm at 1500rpm or something like that so it would be interesting to see a dyno graph of how the extra 50Nm improves the torque profile further still.
I think this was a predictable move by BMW; ensure that at the time of the E92 M3’s launch there’s plenty of separation between it and the 335i, after the M3 becomes more established, lift the 3.0 turbo’s outputs to spice things up a bit.
