does anyone run these they seem to be the way to go,im building a set of 540s talldeck and was thinking of usuing these any pros or cons???

I have run them, they are awesome. super reliable, very clean install, only 2 wires to hook up, just make sure you run a 10g switched power wire from the key to the distributor , dui recoment this so that you get full 12v w/no amp draw for the 50,000volt coil.

All so the come set up nice from dui , custom tuned for your boats power and weight, I ran the clear dis caps, which are great as you can see what going on inside, great to see rotor spin, and see condition of contacts, and water....

The wire they make are the best quality i have ever seen, all numbered, super thick wrapped insolated.

yes i think im going to use those i like the way the wirng is on them

Over 20 years of trouble free use on mine.
I hate to think of how many MSDs or Tbolts I would have gone through.

Yes, very good product.

What are guys doin for a rev limiter with the DUI?

DUI has a rev module/limiter that installs inside the distributor; but, when I ordered mine they were out them and on back order so they sent me an external box, and three different rpm chips. I ordered the whole set for my 509 which included the distributor, curved to my motor specs, live wires, and rev box with chips. Best decision I've made and so far. Its been a great product!!

Here's the link to the distributor if you scroll down to the bottom you'll see the dyna module rev limiter.

i didnt run a rev limiter on mine with the dui. my hands always on the sticks.


whats nice, is if you every have a problem with a dui any part can be bought at autozone to get you back on the water till you get a replacment part from dui. msd's fail so much, all my buddies carry extra pickups, coils, and boxes....
