Have a 2004 Speedster 160 with Merc 240 EFI, have been searching info on a Dyna Boost, has anyone had any experiences with this stuff. Can it harm the engine and does it do what the adds say.

This is a new one to me -- is this some type of fuel additive or a performance chip?

I have never talked to anyone who has tried one, but I highly doubt it does anything more than make the boat run a bit rich. The Dynaboost just taps in to the ambient air temperature sensor and tells the ECM the wrong air temp in order to enrich the mixture. The problem is without forcing more air in at the same time the tiny bit of extra fuel will do nothing but make the engine run a bit rich. Remember your ECM is already running your engine at the ideal 14:1 AF ratio.
