I actually came away with 20BHP Less than what I went in with but with a Map that was much safer, Also came away with a Map that offered far more drive-ability! Partial Throttle has improved greatly. Very happy indeed and today was my 4th visit to R-Tech on 4 different cars.
I appreciate the market for other tuners and there needs to be variety as different people like different things and I wont knock other maps just because they are not to my taste, I have driven TFSI's with other brands of Software fitted and for me ever since taking my first Golf Edition 30 to R-Tech and been very impressed with the results I have remained loyal to them ever since.
After my car was road tested and further logging was done the Map was then altered a couple of times to get around the K04 Surge Point.
I drove home feeling very valued and that I had received excellent service, Also that I was appreciated as a customer and what I wanted was listened to and reflected in the end result.

^THIS.
R-Tech are all about delivering what the customer wants, and shouldn't be seen to be pushing the boundaries of safety & component limits - they aren't a 'one trick pony' that can only do balls out power, unfortunately 99% of people want that, and so r-tech gets the reputation of pushing the boundaries of what's safe, which isn't ever the case. Bonelorry's post above reinforces this point - ask for what you want, and ye shall get :drinking:
R-Tech typically make the same power as others using less boost, and going linear (their preferred approach) is less stressful than the aggressive torque delivery of Revo & superchips.
Their TTE420 maps are almost always de-tuned from the maximum headline figures to something which is more drivable, and less stressful on the engines components - Niki is very conscious of damaging engines, and will not map anything in which has high potential to cause damage, unless the owner is willing to accept the risk (which is made very clear).
Saintsteve:
I opted for a linear remap from RTech, cannot fault it and power is very useable with the 338bhp and 335 lb ft it produces. Less wheel hop is one thing that I find a lot easier to control over have a more aggressive remap with a massive Torque spike which wasn't controllable off the line from another un named popular Tuner.
I also had the DSG remapped to compliment the type of map installed.

In comparison to which other vendors tune? And are the engines and supporting mods in question identical, and done on the same dyno on the same day?
If that is the case, then there is no reason why R-Tech's tune would make more than a different vendor's. Air in, burn it, exhaust out. There are no miracles on offer which defy physics.
All things being equal, the most likely reason for the discrepancies is dyno truthfulness.
Turbo engines should have an aggressive delivery imo, otherwise get a big n'asp engine :smiley:

Superchips is a great example for this scenario. See here: http://www.mk5golfgti.co.uk/forum/index.php?topic=65077.0. 1.7 bar vs 1.3 bar :happy2: - another example of R-Tech de-tuning elements of the map to make it safe, further dispelling the rumour that all R-Tech do is do is max everything out beyond the other mainstream tuners.
So much more to tuning than just adding air in, burning it and pushing it out. No other tuner uses the VVT to aid turbo spool. . . It's no miracle, but hours of development identify these little nuggets of progress.
Most tuners did a few hours of development, release a tune then walk away. Only when you personally tune & fettle hundreds of different cars a year can you really find out what these engines have to offer.
Notice the v3.4 APR tune follows a very similar graph to the map James had on his K04 with WMI in here: http://www.mk5golfgti.co.uk/forum/index.php/topic,43854.msg601159.html#msg601159
This made pretty much as much power & torque as a BT setup, and got a few surprised looks at the JKM Dyno day. It's not a sensible map for every day use, but shows what can be done by spooling the turbo one else, 'table-topping' boost and then spooling again. This was a development setup to see what these turbos & engines can do. 400bhp & 450lb/ft at 4,500rpm is crazy :grin:

Oh gawd.. it's turned into one of those threads!
My 2p (regarding partial throttle). R-Tech maps are the only maps I've had that are completely smooth and predictable going through various throttle/load positions. There's none of that sudden boost out of nowhere situation when you just want to get moving without drama. Other maps always seemed to have a bit of 'indecision' about them. Easily confused.
It's worth noting that the other maps I'm talking about were on different engines. 1.8T, AJM, etc. So my point may well be completely invalid!
It's only k03 Stage 2 so I don't think it's got 1:1 throttle mapping, but for what it is, it's very good. I can't pick any faults in it.
If and when I go k04 I have the option of having the mapping done along with the hardware, at Statller. I assume it'd be Revo. To be honest I'm 50/50. Would I gain that much by staying with R-Tech? Possibly. Would there be an advantage to using the same guy for hardware and software? Probably. If any issues arose after the conversion I'd imagine it'd be easier to diagnose and sort by effectively trusting Steve with the whole responsibility from the start. Best way I could word it but you get my point.
When I had misfire issues on the current map I got the impression there was only so much Steve felt he could investigate as it wasn't 'his' map. He did infer that the R-Tech map was running a lot of timing and could have been causing an issue. Which kind of put me at odds between Statller and R-Tech. Ultimately it got sorted with refurbed injectors but keeping it all in-house probably has its merits in some cases.
Anyway, my point is that it's not always as black and white as saying tuner A is 'better' than tuner B.
Bit of a ramble that
