Got mine done yesterday - definitely feels a bit more solid but ... there's still a damn knock audible there, I'm now guessing it's the other known suspension issue, the struts that need replaced.
Hypertech were good enough, when having arrived late yesterday as I took the scenic route to Bonnybridge (!) I asked if they could look at recharging the a/c, they discovered that the system has a leak so it wasn't a nice, simple (read cheap) job to resolve. dash and blast...
More funds to head out of my bank account soon it seems ....
