Long time Seadoo enthusiast here with new 60hp spark purchase. I know that the V-tech tune is the first order of business. Is it 109hp? Has anyone felt a real "seat of the pants" difference in adding a Riva free-flow intake then later adding the exhaust? Trying to justify the extra $400 to add the intake and exhaust. Doesn't seem worth it for 1-2 hp. I would rather put that into trim tabs/ride plate. Also wondering what total HP would be with all three mods. Thanks yall!
