    Worth the money???

    Im am considering picking up one of these two options below, but before I do I'm wondering if anyone has has any experience with either or if you think it would even be worth it. It would be going into my 25ZX with a 502mpi that is basically stock.

    neither ,,if its for your zx you wont notice the performance.. too little of hp gain for the money..save your money and invest in a pro charger or a Whipple.one of those will give you a 15 mph increase..

    Thats the advise I was looking for. Thanks. I have always heard that the k&n flame arresters don't really add anything, but was not sure if I added the fuel pressure regulator as well.

    What fix said. Drive the boat for a season or so and then figure out how fast you want to go. You will not even notice the small mods.

    It takes MUCHO $$$ to get any real noticeable gains, some say $1,000 a mile. I think that is high but the faster you want a boat to go the higher the $ figure climbs, besides there is always someone faster. Shoot for being content with the performance you need not what you dream of.
