Just an update: I'm happy with the unplugged valves. It seems to be the correct balance for me. @dasquade : Don't worry, It's my most sensible car, but I haven't bought it to pootle around in.

After Max's post and a quick Google, I think you firstly deserve an FON, and then you need to rule 1 your C7 and other cars

Welcome along.
