Re: Losing power over 6k rpm in 1st gear????
The tachometer has needle damping (like most gauges), and the rate of change of rpm in 1st at WOT results in tach needle position lag. When it looks like you're just getting a bit over 6k, you are already at redline. The rev limiter is kicking in, and that is what you are feeling as a power loss. (I'm guessing this is your situation anyway). It took me a while to get down just where to shift 1-2 in the M5 because of this issue. The higher gears don't exhibit this behavior as the needle's rate of change is slower. My V70R behaves exactly the same way, and I was fortunate to talk with Hans Nilsson (Volvo's R "guru") about it -- hence where I learned of this issue. I'm extrapolating what he told me to the M5 (he did mention that it is a common issue in other high performance cars).
