Has anybody heard of this outfit or tired their products? http://www.dmsautomotive.com/index.asp?upid=2
They claim " Maserati Quatroporte upgrade for engine and gearbox software transforms car "More power with a smoother precise shift""
And in Car Magazine (UK)'s advertisement they said the the power output of the Gransport and Quattroporte is 438bhp.
i have approached them before, but they said that our gas here's octane level (94) is not good enough to see that 438bhp.
at least they are honest about it.
