Just use the 0280158040.
I had the same dilemma long ago with RS6 and RS4 - you're overthinking it.
The 0280158040 does a very good job atomizing and if you have any kind of load on the engine everything gets sucked inside anyway.
Yes you will need to tune ESUK some. And if for some reason you have some issues on idle (but you shouldn't) you can also bump up KFMRES a little and play with cam advance to put a little more load on the engine.
But really it is possible to make them run just as well as stock from a "feel" point of view.
ye thats what some collegues told me today also.
i just bought the 0280158123, but these should be as good as the 980ccm cuz of the 90° Delta.
another friend told me they , just to put in the 630 Siemens DEKA.
Anybody ever tried the 750ccm Denso ones?
