Anyone ever used a tunit box before?

http://www.tunit.com/

Hearing good things about them, didnt know if it would be worth looking at one for my 1.9Td T4.

Cheers.

An expensive resistor that. All it does is change the voltage from the fuel rail sensor so the ecu thinks fuel rail pressure is a bit low so compensates by opening the injectors longer.

A proper re-map will always be better

I would rather lose by a mile because i built my own car, than win by an inch because someone else built it for me.

That's fine, but I've had them on loads of vauxhalls and not had a problem so far. Not quite as good a s a remap but not far off.

With the vauxhall ones specifically, there are loads about so always cheap on ebay.
