I got an bone stock (enginewise) 1996 seadoo xp. I'm planning to upgrade the ignition with a MSD enhancer. I understand it will also eliminate the D.E.S.S. But I live in Aruba so I pay almost triple what you guys pay in the U.S. for these parts (shipping, duty etc). So before I lay down the cash dor it, does it really make a difference in the performance? or does it require other upgrades in order to have a difference in performance?
