is that "claimed bhp" or actual timed performance etc?There's no other company getting the same performance figures over here from tuned S4/RS4's. .

Rolling Road printouts, FATS times (most reliable method for comparing power outputs of S4's), 1/4 mile results, etc.
I was happy with the 12.8 I managed at Santa Pod earlier in the year, especially seeing as how I asked for a low boost map from MRC (19psi-17psi). There were other MRC tuned K04 cars (full weight) running 12.6. I think Brett (CELSISONE on here) has managed much better times than that with his MRC tuned S4.
MRC have had 350bhp from K03'd S4's and over 500bhp out of plain K04'd S4's. You show me another UK tuner who's managed that and I will eat the hat of your choice.
Stage 2 is dowmpipes, decat the precats and upgraded DVs at the minimum.
MRC are well respected here and on SRS. I don't think you can go far wrong on a std map, but as stated take figures with a pinch of salt due to too many variables to list on here.
The car will produce more power, it will have better throttle response, it "may" have better economy. Well worth the money mapping or chipping any turbo car IMHO
Stage 2 depends on what car you have!
I've used MRC on a number of occasions. For the 2.7T engines there is no one better in the UK. There's no other company getting the same performance figures over here from tuned S4/RS4's. And their customer service is excellent.
i cant see that it will get upgraded dv's and de cats, as its only £85 +vat more than yhe stage 1....
For an extra 85quid?
The extra power gained from a "custom map" will simply be down to pushing more boost on a stock engine.
aragornHowever i'm sure MRC's "generic" map will be pretty spot on said:having done a bit of research though, it seems they making their claimed power figures using lower boost (which is only a good thing)
what is really needed is a RR day or a shoot out on an air field, but its probably all been done before

Just a shame they are nowhere near me in rural Carmarthenshire...
The FATS time is a 4000rpm to 6000rpm pull in 3rd iirc, so ye probably around 60-90ish...

Nah, not worth it.
End of the day, its a MAF fuelled engine, if your motor is flowing 1% more air (because its a "goodun"), it will recieve 1% more fuel. You think audi map each car differently? No. They build the ECU with some learning capabilities, and put the same program on them all.

The ECU doesn't have much scope to advance timing on
race gas for example.
