My comment wasn't an 'anti' comment by the way, just giving you something to think about. I'm ordering one for my R.
I have been warned that VCDS may be able to pick up that one has been used and flag the car, although not sure how much of that was scare mongering. I'm yet to find feedback from anyone that has had one of these boxes and a VCDS check done.
Saying that I'm not too concerned as have heard nothing but positive feedback from users of DTUK.
I trial ran DTUK box on a friends mk7 GTI 'company development car' which they had for a few weeks around Xmas and New Year time. They've since taken delivery of a 14 plate GTI non PP in identical spec too as they were so impressed with that car.
Anyway, I fitted the box to that car for a while and when I removed it again before the car left their tenure I ran a VCDS scan on it and nothing showed out of the ordinary, no fault codes whatsoever but maybe if you ran VCDS logs of it during driving you could see slightly different values to a standard car possibly? I can't answer that as I didn't get chance to try it.
So basically fault code wise the box is invisible to VCDS at present.
However dealer diagnostics
might well be able to pick up its presence as boost levels will differ to standard. But they'd have to be looking for it, and I don't see why they'd look for it unless they had a beef with you.
I can't see how the DTUK box could possibly cause extra wear on the car unless you drove like an idiot all of the time and to be honest the standard car would suffer likewise if you did.
The DTUK box doesn't spin the turbo crazy fast at 2000rpm like a lot of remaps so the torque and power graphs look pretty much like standard but you just get a bit more, thus you won't be lunching dump valves and clutches as the power increase is very subtle and just feels factory smooth.
Fuel economy, as above, it was pretty much the same as before but this was a very low mileage car and wasn't thrashed.
Insurance wise you'd be silly not to inform your insurer as you have a big plastic box with a light on it and a wiring loom to give the game away! Andrew at DTUK can advise on insurance anyway.
There's a forum discount available from DTUK.
