@guffy: Thanks for the comment.
In regards to the clean, they didn't put mine on the dyno after the clean, but if you check out their Facebook page, they have plenty of cars which show figures before and after a clean.

From what I've read/seen, the loss depends on the mileage and how the car has been driven throughout it's life - if it has been driven hard often, there is less of a build up (am I right?). It may be worth getting it on a dyno to see where it's at.Cleaning Intake Ports
Ports cleaned, valve and valve seats cleaned.

As for who else does this, not sure myself on that one, but I'm sure someone else on here could advise on that.
