R-Tech are superb! Where Revo let me down with power, R-Tech came through for me
I'm looking at getting the Vito remapped so I'd be interested if you find anywhere.
I've seen DP Auto Services in Sharnford that seem to remap a lot of different vehicles including vans/commercial but they're lack of dyno concerns me a little.
Without a dyno to do test runs they'll simply be loading a file of an existing map. Granted they may also do a bit of road testing but that would get nowhere near the accuracy of a dyno run before and after changing each parameter.
I thought that would be the case.
The vans use the same engine and turbo but come with different power outputs for different models.
I assume they just load a standard higher output map with minimal road testing.
The large majority of these companies will be using "tune files" developed by a larger company and simply act as a reseller.
They're generally extensively tested. We start a project along these lines next week. One car, one engine, no hardware changes and it'll be around 40 hours of development
Does anyone have any recommendations for Mercedes tuners? I have been googling about but just coming up with all my local ones and the bigger names. Really unsure what is good and bad.
What I know from modding a car - when you start mapping them/modding them, they break, more often then not or have nitty little problems which are annoying to diagnose.
Maybe I’ve been lucky with my last few cars then, but reputable remaps (Revo in my case) have brought nothing but benefits.
Its generally on older cars. Hoses failings, seals failing etc just niggly bits.

But this is pretty much the definition of why older cars loose value so quickly, they get minor irritating things go wrong, seals, hoses etc are exactly the things that go brittle with age and general wear and need replacing. At this point for many people they are unreliable and hence not worth as much.
Most of the extra stresses will be seen by the internals, bearings, piston rings etc, a bit will pass to the cooling system, a bit to the clutch/gearbox. So increase the stress on an already ageing system you should expect that you will bring forwards the failing components in those areas.
As long as you stick with a reputable tuner you should be fine. My last car was mapped with just a Superchips Bluefin device and i drove about 50k miles and no issues (25k a year), And my car before that had a complete custom map and again was fine for 3 years, no issues. My current car which has just turned 1 will be getting remapped soon as wellSee this is the problem, my car is still under 3 years old (just) and so all perishables should still be just fine which makes me think I should do it.
I'm definitely considering a Revo map, they have done pretty extensive testing and development with their development car.
Some decent gains to be had on my A4. Revo did post a controversial video showing their stage 1 producing 333Bhp and beating an S4. Not sure what they did to make that happen since the numbers don't support it but hey, shows that the A4 can be pretty nippy either way.
Makes sense, minor other tweaks, but the 2.0TFsi is used in things like the TTS and pumping out that sort of HP
Gearing could make a difference as well?
