As some of you know, my 93 3500 CC Dually now has a 6.2. and that I used the 6.5 intake, exhaust, IP and lines. At the time of the build, I did not know that the 6.2 injectors have a lower pop pressure than the 6.5 injectors, so I left the 6.2 injectors in the 6.2 heads when I put them on. So my near future plan is to have my6.5 injectors tested, and if ok, install them.

I have tried to turn up my IP, but when I could not get the fuel screw to turn. I put a good deal of effort into it, but I figuree I should leave it alone before something got broken. So I plan to change the Ip for another one that I have. I know the fuel screw will turn on it, but I honestly dont know if the pump works.

I think that with those things changed, it should run alot stronger.

Also, I changed out my turbomaster spring for another one I had in the junk drawer, smaller diameter, but longer and stiffer, and it now runs 9 psi under load. It runs a LOT stronger.

This thing will never be a speed demon, nor will it ever be quick off the line. It weighs 6200-6300 pounds, it s a freaking tank. I just dont want to be the slow guy holding up traffic.

 

Be cautious,I believe that there is a difference with the threads on injectors between the 6.2 heads and the 6.5's.
