I know there is lots of talent on this sight. Anyone set up to recalibrate a 911 tach?

I am doing a /6 conversion for my customer and this tach reads low, p/n 911.641.301.01. Both Hollywood and Palo Alto are quoting a long turnaround time.

Thanks Brad

Tachadapt can do that ,easy setting as per intsructions,I agree with timothy,my tach wouldn't respond,fitted tachadapt and it worked but really unstable,talked to Bob and he said it was (IMG:style_emoticons/default/stromberg.gif) ,PO mentioned he didn't know if it was any good but gave it with the car.
It reads low @ idle and is really unstable unless constant RPM is maintained.
