Hi Fisher,

as far as i know the new pulley has diameter 56,5mm, serial pully 63mm? (don´t know exactly). Usually it is installed bei HiTec in Viernheim.

To remove the serial pulley and fit the new one, you need a special tool, because it is friction-locked (shrinkage assembly). It is recommended, to let this work do by specialists, because parts of the front module have to be removed and the engine has to be lifted a little bit to reach the compressor.

If you are an technical expert and you would like to try the alteration on your own, you should read up on this very well. Guess, there are many things that can go wrong.

The quality of the work done by HiTec in Viernheim is afaik very good, because they did this remount very often. But i understand this way may be too far to go for you.

The MTH software also changes the limits of DSC. Franz is setting them up to 100Nm slip.

The HiTec Tuning kit is absolute good value. Many cars run with this alternation and afaik no one talked about problems until today. A few days ago, i had the possibility to drive HiTec on my own and it was really fun. Will do it as well.

I hope, i could give you some help.
