Wouldn't see any problems in driving it normally to get it tuned, even if it was a bit larger injectors.
That's what I think too, be more bothered if flow rate was less. But why would anyone do that?

As has been mentioned if you change your injector for a 'better' one you really need to be changing the mapping to make the most.
I'm using Bosch 'green giant' 0280155968 injectors which 'bolt in' and use better multi hole atomised spray technology, however i'm also using MS2 to fire them.

I can say although they are 42lb they are not 'too big' as was historically claimed and my engine idles/cruises fine.

Wow, just looked at the specs on them, about double the flow rate of standard bur as you say the low speed behaviour is more dependent on atomisation capability than anything else which is mainly what got me asking this question.
Wish I had the engine to use them!
What sort of output is yours.

4.6 supercharged Rover V8. Haven't yet measured the power - but from engine calculations I've done should be around 400bhp.
I believe they are popular in the US so they are generally well priced.

That must be incredible in a car that light, think I've had a skate-board which was heavier!

Certainly concentrates the mind!
Weighed around 650kg when it was SVA'd.

About 200KG lighter than mine and double the power. I'm guessing you avoid wet weather!

Now i've got some softer/track biased 255 rear tyres which are much better and on a nice warm day really grip well - on a cold autumn day you need to be 'gentle'!
Only driven in the wet once - on a road trip to Le-Mans a few years ago - with the old 3.5 engine - 'scary'! aquaplaning very easily at 40mph on the motorway! my mate in the Rover 'support car' was wondering what I was upto as I disappeared in his rear view mirror going sideways! :lol:
Light cars with wide tyres are not ideal in standing water!
