Can you tune it up higher? Sure - but at the cost of longevity. The N55 ain't the N54....which had forged internals and could make substantially more power without upgrading those same internals.

Yes, this company is Tuningwerk. It's the only company which was able to kill a N55 with light mods. It doesn't mean anything compared to thousands of 400+ N55 running without problems.

Yes, it is the brazilian company ACF. It is the world record on N55, if I remember well it's almost 650whp.
Can't wait to see some dyno and 1/4 mile of tuned M2s.
Just for comparison, stage 1 tune on RS3/TTRS gives 420-430 crank hp.
