Have already asked Ralph, no comment. I think the mob I will be taking mine to is Cornell's out in the north west of Melb. There was a mob down in Dandenong that had a handle on the Standyne pumps, but I think they have changed hands or something like that and the outcome is not so good. @Rossco had his truck tuned there recently with good results and they have a dyno as well. I don't know if the fella in Lilydale would be interested.
