Tbh on some cams, even with a proper map it will idle like a pig. I don't know much about these cams though so don't know how severe they are.

Heh yeah for sure, these are ph3's so far as you can go on standard pistons....which other people claim to run fine...

The only explanation I have, is that they are running verniers, and adjusting cam timing (and likely loosing power) to achieve an idle... Thats the only way I can think  there doing it...

I must admit, I didnt realise the cams were making quite such a difference, it really is a different engine now...

To be honest mate, without just blatantly slagging off 106owners (ok, so i kind of am), a lot on them on there, their idea of running well and idling is substantially different to most of ours. I bet a lot with PH3s in their engines on stock mapping and timing just put up with it and think it sounds more racecar when its struggling to idle.
