Not sure who Unit20 use for tuning now, still revo? Think they used to offer Viper as well?
MRC are masters of tuning, but Unit20 for servicing as their customer service is soooooo much better.

Same here as everyone else - MRC are by far the best RS6 tuning company available in the UK but I found them to be just "OK" or sometimes less for everyday garage work like servicing, faults and especially the bigger things like engine rebuilds etc. So, of the two, I much prefer Unit20 for that sort of work.

Do Unit 20 have a rolling road, or do they just do stage 1 tunes?

MRC seem to have VAG stage 3 tunes nailed. These are great examples:

Golf R7 TT V5 Stage 3: 278 bhp/l @ 6900, 320 Nm/l @ 2900


Golf R7 2.5 TTE777: 303 bhp/l @ 7500, 346 Nm/l @ 3500


RS6 V10 TTE1000: 216 bhp/l @ 6900, 254 Nm/l @ 3100


They all have high specific outputs AND wide useable power bands - none of that "all-or-nothing" delivery.

There are other tuners and other cars like RS4's and GTR's that have high specific outputs, but they have the torque and power peaks close together, like this example, which must have had the wastegate welded shut:

Thanks everyone
