Hello Adam and welcome to the A2OC
As ULP says, the Tank has indeed been seen to by Simon and it's probably the best this I've ever done or had done to the car - RNS-E included.
The performance now from this little 1.4 litre 3-pot diesel car is simply astounding and everyone who has been in it always comments on how surprised they are.
I've probably gotten quite used to the performance now, in comparison to anyone that I take out for a spin, but even so, I still get a little rush from the Tank when some spotty 'erbet in a bodykitted CorSaxo (or similar) decides to have a go (yes I know I should rise above it!). It's great to see the look on their greasy baseball cap framed faces (in my rear-view mirror) when they are left sucking up a great cloud of diesel fumes left in my wake AND they are then out-braked into the bargain.
So in conclusion - GET IT DONE.
NOW!
Cheers,
Mike
