Hi All,

Has anyone used these before or can offer any wisdom

Thanks

I've had the TDI one on 335d and the DTUK one on M40d, both are good.

I've actually got the DTUK one with Bluetooth control not fitted to the car currently, as new in original box, that I'd be willing to sell for £300 including delivery if you're interested.

326-398 ps :-o, not to mention the talks ;-)

I mean - the beast is fast as is, but that must be cray!

TDI Tuning always way overstate their performance gains, I think DTUK's 375bhp is far more believable.

And yes it is crazy, I timed 0-60 at 3.9secs, on winter tyres!

How are you liking the tune?

[jlcrompton]

For me i love it, well worth the money.
The hit it gives you when your flooring it from the light is amazing.
I did a few runs for work going from Bolton to Kent doing 65mph with out the tune and was getting at best 55MPG, with the tune on I had to do the same trip and got 49MPG. So it can be just as good on fuel if you take you time and think about what your doing.
