Rev limiter kicks in
Discussion
If you're on the standard TVR 14CUX ecu I would have thought that it's incorporated into the map on there, is it a standard engine and ecu?
Has it always been where it is and is it constantly there? Iirc the standard limit is set at 6500rpm and there's no point in it being higher than that as peak power and torque is around 5500rpm, yours did sound really low though, what does the needle say when you hit it?
The other thing is, specially if this is something new that is happening and it's not consistent, is that it's not the rev limiter kicking in and you've got a massive misfire going on at high revs.

I possibly think the latter comment?Has it always been where it is and is it constantly there?

What do i do
That does sound like a hard cut rev limiter around 5k, your other couple of videos you're short shifting before it too. You'll have a sex wee if you fix it, you're missing the fun part of the rev range

I'm at the other end of the country and going from a youtube video, but if this has only just started happening I would be looking at spark, probably the dizzy/rotor arm/sensor if it doesn't randomly misfire whilst normally running. You could probably do with roverguage so that you can see if its throwing any error codes.
What you really need is someone more local to have a poke around though.

Not really http://youtu.be/I__qGNTzyn4?t=10s
by 5.8/6k even on the HC its all over you only really it the rev limiter in the 1st 2 gears if your going for it if your trying to hang the motor out to bang the limiter in any gear above this your just pissing in the wind and probably need to learn how to drive a car quickly 
Yeah, but that 'sounds and looks' a lot lower than 6k, I agree that there isn't loads more power at the top but that just seems way low. I know it's sometimes hard to gauge things just from a video, but that doesn't sound even slightly close to where mine cuts in.
I've been sitting here watching youtube videos of chimaeras going up the drag strip and it it so hard to tell, it sounds like people are changing up where your rev limiter is cutting in. You need to bee looking at the needle and tell us what it's cutting in at

ks to me but you never know with these cars! My first ('93) chim 400 had a range rover ecu and the rev limiter came in around 5500. When I got a proper tvr ecu in there it revved to 6500 and the power kept climbing to around 6k.
Agreed Sardonicus the power is over by then but there is something very special about a rover v8 with no cats and sleeved silencers revving that high.

Now I don't know what to think 
I always thought that mine was higher. I only ever occasionally hit it, normally in 2nd whilst being a hooligan so I'm rarely looking at the gauge.
5900rpm in 3rd according to the needle. Excuse the dash, interior is on the to do list

Yours may be correct, let us know where it is set

When I first had a v8 discovery years ago. I had an odd missfire at full throttle when over taking, that turned out to be the rev limiter kicking in lol... on the disco it was set lower at about 5.5.
i have seen some tvrs with the lover rev limit, i.e. still got the original landrover map!!!
