Meh, newer high torque DI petrols sit there using Launch Control etc which is still fuel/spark cut limiting... They also sit there at 6000rpm battering off a bouncing limiter, it's just that until recently with Petrols you've not been able to cut the engine torque back cleanly, but look at fly-by-wire MED7, they cut the throttle back to stop a bouncing limiter... Tailing off to a governed speed is preferable in the world of engine calibration, but does just feel shite...
I wouldn't be too concerned about it, and especially seeing the quantities going in, it's hardly like you're putting in 80mm^3 and cutting it in and out... You see the TDi guys with proper "popcorn" limiters injecting that sorta quantity straight again afterwards to get the "pop" noise you get as it hits the limiter, it's probably not good for it, but at the same time, you see petrols running anti-lag and "pops and bangs" remaps regularly and all sorts of wierd timing adjustments on the limiter and at transient throttle changes to make cool noises... I think that yes, there's a bit much worrying there, don't get me wrong, I don't think it should be a "standard" thing on a map - but for a customer who clearly is into extracting the maximum performance whilst knowing there's the potential for sacrificing reliability - is it that bad!?
