Yes you do. Cost me an extra £26 on my B7. Fuel economy was unchanged...Do you have to tell your insurance that you have remapped? Will it be increased?
What about fuel consumption?
I just got a tuning box from DtUK. It arrived this morning, fitted in 5 mins and the car drives like a dream. It may be an easy option for you.
Well that's a bit of a buzz kill. I thought these boxes were a bit more than the cheap resistor boxes from eBay? What version of the box did you have mate?I managed to rag the car around so much, enjoying the extra performance of the DTUK box that I filled the DPF in less than 1 tank!! So don't get too carried away cos it's not remapped your car, it's just tricked the fuel pressure sensor, to increase the pressure, so it squirts in more fuel.
The map for fuel timing and duration is unchanged. Whereas a remap changes the actual fuel mapping.
But there is 3 maps programmed into the box. All with rolling road results which if the car was just getting over fuelled it wouldn't show genuine increase in bhp and torque? Also the 3 maps deliver the extra power differently with different power curves, would an over fuelling box be able to do this?To be fair it was in 2008, so things may have moved on since then, but at the end of the day the boxes work by tricking the ECU, not by fine tuning it.
Some good reading although I'm not sure I understand it all. Modern boxes not that bad, but not as good as a remap?Worth a read of this thread.

Interesting discussion on that link and confirms what I've been thinking about tuning boxes. I can't see how fooling the ecu to add more fuel and more boost as these boxes do can give a finely tuned map. it's certainly a crude way of tuning, it must work ok as there are many happy customers. I for one will be having my 3.0tdi remapped and I have narrowed it down to either ADS in Preston who does revo or I'll be going to unicorn who come highly recommend here.Worth a read of this thread.
