so is it safe to assume that the reason BMW made the N55 was to discourage tuning?

I'm sure it was to cut costs. I'm learning more about the platform by the day but there isn't a lot of benefit in publicly sharing much info if you catch my drift. At this point I will say if you're deciding between an N54 and an N55 go the N54 route.

Could the lag have anything to do with DCT electronics limiting things? Just curious.

I know nothing about the N55 but is the Turbo located on top of the engine (like easy access)?? Because in that case the N55 might pan out to be better to work on for BIG gains than the N54.........

Doesn't look any easier to reach than an N54 but haven't torn it down yet to really check.

The best things about these cars here in the US, is that it has the option of having a DCT 7-speed. The 335is has the best of both worlds (N54 & 7-Speed DCT).

I cancelled an N55 build order and bought an N54 car on Terry's advice.

Any info on the turbo? 1) Who makes it (MHI again?) 2) how many mm compressor inlet? That at least says something about top-end power.

I'm sure it will work out ok. People always freak when a new platform comes out. I've got faith in you Terry. Beat beat brand "P" to the big numbers on N55 first!

Not worried about brand "P" at all. We've got some new hardware in the works that has their number. Get ready to say good bye to $1000 tunes.

But to get on topic for the N55 we're going to offer 3 stages. We're developing/tuning the first stage now. When that is done and we have something safe and powerful for our N55 customers we'll get to work on Stage 2. And those Stage 1 customers will be able to pay the difference to upgrade when Stage 2 is ready. And so forth to Stage 3.

Not good.

MAF measuring airflow. Say we trick it with the tune to allow a BOV to work there is also no easy vacuum line pickup.
