I hate dump valves!!! I don't run one...

Rolling road set ups are a waste of time to be honest cos it isn't a real world situation. Chances are, after an RR set up, it will run lean on the road and risk melt down.

Not sure about Interpro to be honest either. Don't think anyone on here uses them. My own personnal choice is Stu and Kenny at Motorsport Developments. There is Karl Norris in Coventry who is also very good at his job.
