Yeah Classic Performance.
The guy used to operate the dyno at Graeme West workshop and then opened up his own place down Hackham way.
I take my GTR there now since Boostworx moved 394857390487503875k's up north. Awesome service and awesome people they even gave me a tour of the workshop and dyno cell when I first went there.
Oh and their dyno cell is AMAZING. If I could live in it, I would. I would even hold my babies in there. If the cell had a womb.
