Note the section about ‘noise cameras’ issuing tickets. Not sure how my Alfa 4C with its race exhaust will fare baronbennyt said:
So we need to be at 68db by 2026! For comparison 70bd is equivalent to a shower or dishwasher ...What are track limits - 95db? Again for comparison 95db is 8 times as loud as 70 dB.
Sad times for petrol heads.

Love the blue, couldnt find that colour when getting ours, awesome cars, this is one of the best cars ive ever owned (and thats many), on track or tour its a beast at both.
Didnt want the full blown gtr as needed it to be a bit more user friendly but i did want the same engine & power so i plumped for the gtc which is identical to the gtr (unlike the std or s variants) under the hood bar mapping, turbo & injectors are different on the std & s (so i was told)
Anyway, lots of track days under its belt now, sticky cup2s fitted as per the gtr & today i got her mapped to push things on a bit more..
Great results by DMS, never knew the torque limiter was so severe!

Wow, fantastic gains. Any concerns about reliability? I guess DMS have done many such conversions to the 4.0L V8 twin turbo that they should know.

They have done a fair few gtrs apparently with the same results, i’m assuming with no issues thereafter..
If you look at where mercedes has gone with the development of this engine though, it produces 640hp in the gt 4 door and that has the same gearbox as the gt coupe, not seen a torque curve for this car to know if its torque limited in the same way, be interesting to see.

My concern and question to dms was why the torque limiter was so severe, i was thinking gearbox woes with that kind of torque.. they said it was just mercedes controlling the mapping to allow space in the market for the gtr, i sort of see that but when i asked how severe the limiter was on the gtr they said it was very similar, so i duno..

Would you wholeheartedly recommend the DMS Stage 1? They have done a fair few gtrs apparently with the same results, i’m assuming with no issues thereafter..

As for the map, early days, only had ot done today and havent even opened it up yet as it was nose to tail traffic on the way home so i couldn't recommend yet i’m afraid, the jury is out..

The establishment is top notch, very confidence inspiring and they map many high end cars, the facility is fantastic and theyve been mapping for as many years as i can remember and i’m 50, never heard a bad word about them.

Let us know what you think of the re-map once you’ve had a chance to try it out properly.As for the map, early days, only had ot done today and havent even opened it up yet as it was nose to tail traffic on the way home so i couldn't recommend yet i’m afraid, the jury is out..
Still perfectly tractable to bumble around in, still easy to drive smoothly with no shunting (had read renntechs map caused shunting)
On the cup2s it handles full deploy 2nd gear >
The torque difference is huge but it carry’s on building harder and harder and then the hp takes over toward the red line.
Big difference to std but certainly doesn’t overwhelm the chassis or tires, std road tires would be different I’m sure. Very happy so far, track tomorrow so that’ll be interesting.
