Stock the car runs out of puff a bit after 5500rpm but with improved breathing, i.e DP, TIP, Ram intake & FMIC & more boost it flashes through past 6,000 so fast it makes your head spin. I have the kmh/1000 rpm curves, see attmnt. You'll see that 250 comes up well inside 6500rpm. I've checked my speedo & it reads 1% high, i.e at 100kmh, actual is 99. BTW, speedo accuracy might often improve with tyre expansion at speed, referring to a previous post.
