Ok, just got the wagon back from the tuners. Was running rich as I suspected so that’s all sorted. The guy who did the work is an old school mechanic and was surprised at how good the car drove. Said he had to road test and what better place to go then the drive through bottle shop

. Anyway by his calculations from the dyno run it is making (wait for it) an earth shattering 200 ish hp at the flywheel. Not bad for a relatively stock 253.
That makes me happy. Next stop engineering inspection in Melbourne.
