Ooops forgot one
Stefan,
I suppose comes down to 2 reasons, generally electric pumps are REAL noisy and don't seem to do the distance when used on the street often.
BUT we were shown a pum yesterday no regulator required and QUIET AS
Also his current mechanical pump is rated and 200gpm? and on the dyno and street tyres doesn't show any dramas "only" when radials are fitted so possibly standard pick up location or some else?
Bit frustrating but at the end of the day like everything else is only time/money till sorted
