melted piston

Down pipe and intake made the biggest difference on my 97 PSD, the stock down pipe will scare you!!!

The fuel pressure will do little if anything HP wise, it may smooth your idle a little.

You've got to get some guages in there soon, I melted the #7 piston in my 99 PSD running a Superchip programmer. They will get hot! I would suggest a pyro and tranny temp minimum, but if you have a few more $$$ (about 50) add a boost guage too. Keep the pyro under 1250-1300 and the tranny under235-240. Boost guage is mostly a toy but it will tell you if something is wrong, ie leaking somewhere or turbo is going south!

do you know what the cause for the piston melting was

ok guys got my guages in they are working fine. Another ? what do yall think about a propane injection system on my truck with 175000 miles on it

If you run propane on its own, its great!!! If your running a chip or programmer, you need to back it off a little or have the programs writing for Propane. It will raise Cylinder pressures quickly and can blow motors if used too much!!!

The Melting of the piston was from running a POST TURBO PYRO!!!! Don't ever do it!!! Pre turbo is the only way to go... It cost me $3000 to learn that lesson!!!

so dont put in the elbo under the truck then. where is the best place to put the pyro.

No, thats where you want it, what you dont want is to install it in the down pipe... see pic, red is my pyro(drill and clamp), blue is the place to drill and tap for that method, and yellow is where I ran all my wires... this is where you want it.

I have the drill and clamp, some have the drill and tap. Both are the same, read the same and last the same.

But you got to go pre turbo!!!
