    Fuel controller & injectors

    I discovered a little errosion problem on my exhaust manifold. Actually it was Melted residue on the J-pipe from the manifold lip. I'm running a riva vortech wheel, RR intercooler & 3" air intake. It's too lean & is melting the **** out of the lip. Maybe thats why i'm seeing the high 8200 rpm's on the 13/19 3 blade? I'm looking at the R&D fuel controller to help solve this or maybe the 42lb injectors. If I were to get the adjustable controller only, would I be able make it work with the stock injectors? Do injectors & controller need to be installed?

    Here's a pic or 2.

    its is a wear item..it wears. ive seen plenty manifolds that look like that. if you have a good dealer the MIGHT cover it under warranty. it is usually not covered though.

    Are you sure you don't have a clogged fuel filter, dirt injector, or a tank of bad gas?

    Have you ruled out things like this, first?

    No i'm not sure
    No i'm not sure
    Yes, it's chevron 91 so it SHOULD be good

    I can check on it. I have a good dealer & i'm sure he can help out.

    usually not in that time frame. my dad just replaced his manifold today, it looked exactly like yours. he has 150 hours on his though and there might have been some foul play by a shady dealer but thats neither here nor there.

    once it gets to the point were its been heated up and cooled down so many times it gets brittle and just shatters. why yours did at 25 hours im not sure. if you are really worried about running lean get yourself an a/f gauge(mayb soembody would let you borrow one) and double check. but with the mods u are running you should be no were near lean.

    You see that crud on the J pipe in the 1st pic? You have to chizle that stuff off. It's not just breaking away it's melting away. Like a piston with Deto damage.

    I agree! They all look like that after some hard hours. They wear at a faster rate for salt water riders. Are you in salt water?

    By the way, you are not running lean
