I am planning on doing twins in the next month or so and am wondering which injector to go with DDP 3 or 4s?

 

I'm running DDP 5's in mine with a Quick Diesel 64/12 and I love it! I may get a Helix 2 next, but it doesn't smoke much at all. Without my TST on, it barely smokes at all. With twins you wouldn't have any trouble with the 5's, much less the 3's or 4's.

 

Sorry, I just noticed that you have a 12 valve. Disreguard what I posted. I'm not familiar with 12 valves.

 

definately get the 4's... they make awesome power and get great mileage
