have a look here

were your settings tested or just set after mapping with no Rolling Road session?

You need VAGCOM to be able to read the fault code (which will still be stored even though the lights gone off)
as well as to log things like timing pull to see if the REVO settings you have are suitable for your car.

Either the settings are off and need tweaking or the map has highlighted a weakness in your car (coilpack etc)

Cheers chaps,

The Car was not remapped on a rolling road, but the garage took it out post remap to check it out. ( a lesson learned!!)

The petrol looks like a potential issue, I have only driven ~15 miles since the remap and only booted it 5 or6 times.

The car was not up to 90deg it was about 75 when it happend.

I will get a VAGCOM investigation asap.

Don't know if the ed30 engine is different but they are the default settings for normal unleaded. 6,5,9 are settings for superunleaded although 6,6,9 is becoming quite common now and giving very good results

Ok, firstly Exhaust has an 'H' in it!

I took the car back to the tuners AMD in Woking and to be fair they have been a great support and service throughout  the process. Basically the car had been misfiring near the redline. The root cause is due to the VW revision of software on the ECU, there was a period last year of about 3 months where the last of the ED30 and Pirelli editions had the latest VW software, this causes a problem with Revo remaps, the latest 09 plate MK6 Golfs have had this fixed. In essence the fix was to load the latest VW ECU software.

Thanks for all the help!

And  I have stopped buying Sainsburys Performace petrol  :ashamed:

WhiteGTI:
Were you using the tuner "Mega 4" in Woking?

Yeah, if you run it on 99 octane fuel such as Shell or Tesco, then you will be able to bring the timing up a bit, obviously with VAGCOM logs to make sure that the car is still running ok.
