£120 Injectors: What are you paying for?

[CNGBiFuel]

£120 Injectors: You can pay that fo one injector. Or £15 a go.

i suspect the only bloke qualified to answer this properly will be 'classic' but here goes...

You can get 5 injectors all done, on a rail for about £75. Or at the the other end, you won't see even one Keihn for that. I've heard grumblings that the bottom-market stuff isn't really worth touching.

I understand Keihn are top of the heap. At 4-5 times the price of say Valtek or OMVL, is their price warranted?

It gets worse because, it's so confusing.

There's orange dot, browns, yellow. I could go on.

For desireabilty which injectors are best for Volvo engines running LPG when..

1) Money is no object?
2) When you need something to work?
3) Where is the middle ground?
4) The flow-rate?

And the same again, which come good for Volvo engines running CNG when..

A) Money is no object?
B) When you need something to work?
C) Where is the middle ground here?
D) The flow-rate?

i see with Keihn they get rated by kW

Blue Injectors - 52 cc - min power 13 KW - max power 20 KW
Orange Injectors - 63 cc - min power 18 KW - max power 27 KW

But they have a minimum too, so in the above, the Blue just about makes enough for WOT, but Orange won't go below 18kW so won't let a stock V70 @ 103 kW (140 bhp) idle?

Surely, it matters not what the flow-rates are, the ECU will adjust it anyway. Clearly not. I'm confused.
