ive got a few questions about the fuel pressure shim, the 10 k mod and a potentiometer i've read about..
the potentiometer and fuel pressure shim do the same??
and can you do the 10 k and the others??
could you also explain the differences as associated with performance.
and what would the expected gains be??
thanks in advance

I haven't tried the other 2, but I can speak on the 10K mod. It gives you a little rougher/higher idle. It throws a little more smoke out of the tailpipe, and it gives you a quicker throttle response. The idle is a little annoying, and it takes a little harder braking to stop it when your at a slow roll, but to me the snappier(?) response I get from the pedal is worth it. If you don't like it, just take it out.
I don't know a lot about the others so i'll leave that for someone else to comment on.
Good Luck

I have a defuser 18k module, supposed to be simalar to the 10k mod, my truck idles exactly the same with it on, gives is much snappier throttle response, and it was simple to install. I highly reccomend it, it's easy cheap power. I shimmed my fuel regulator to 70psi, it did not seem to make much differance. I dont know what your talking about "potentiometer mod" I'll have to look myself. Have a great day.

i thought the potentiometer was a way to adjust fuel pressure but not sure if i remember correctly.. I cant find where its listed by anyone for sale either
thanks
