yeh they can crack 500hp with a programmer, but their egt's are through the roof, and their valve trains and clutches are hurting...
I can hold 500hp+ output for extended durations because my EGT's are hovering 1100-1200* while theirs are at 1600* ready to melt down lol.
and then there is that whole cracked injector and melted piston business...
It may take far more mods to make power from my truck, but I love my VP truck

they are like the new rice. "cold air intake, exhaust, chip, yay i got a race car" pssh.

I was talking to my neighbor about porting and polishing. He was telling me that if I wanted to do work to the head, I would be better off getting like an 06 style and putting it on my 98.5. He said that the newer heads have larger ports to begin with and stock it produces about 80 more horse without any mods yet. Don't know if you already know this but wanted to share and possibly get feed back to know if it is a good idea.

yes, stock vs stock the 3rd gen head flows better, but it also requires connector tube adapters to be custom made for it, and requires you to buy a new head...both increase cost significantly. you will also need to notch out a few water jackets and oil passages to be larger so they line up with the 2nd gen block.
it is usually more cost effective to have your own head done.
also cumminsperformanceparts sells a "race head" for about $3700. head has O-rings cut into it, port and polish job done, intake manifold milled off and choice of side draft or runner style intake manifolds to be put on. comes with valves and 110# springs pre-installed. He also may have done valve work too...it doesn't specify...

Thank you, this all sounds like great advice. Do you have any insight to the twin ram or the custom header style intake where they cut off the intake plenum? My understanding is that it improves airflow to the 5/6 cylinders that would normally be starved. I also herd that it isn't needed unless pushing a great amount of power. The Youtube video on the Black Betty project, the guy says that he will get +150 horse not even including port/polishing. Is that actually an increase or will I only notice that power with more fuel, where as the air is no longer the restriction.

My 12 valve, though, gets hot if I stay in it more than about 10 seconds. I'm contemplating pulling the #100 fuel plate out and putting the stock one back in to see what that does for me.

My VE pumped 12v never breaks 1200*, moving a lot of fuel and spooling compounds with ease. And I can tune it with a screwdriver ![Big Grin](https://dodgeforum.com/forum/images/smilies/biggrin.gif)
My buddies '08 6.7 though, with nothing but edge tuner, hits 1400* under moderste throttle, i have seen it over 1600*. Yuck.

I have the Edge Attitude with a K&N drop in and intake debaffle. I towed for the first time last weekend and hit over 1400* a few times. This is pulling a 9000# 5th wheel over Mt. Hood.
I am going to do the exaust deletes and see what happens to the EGT's.
I just hope I don't leave puddles of "RICE" everywhere I go!
I realize that 5" turbo back (no muffler) will flow better and get lower EGT, but is it a huge temp difference from just doing a 4" deletes?
I have a guy that will do the 4" cat/muffler delete for $110.
Kinda hard to pass up a deal like that.

I have 5" because I'm running compound twins. my S475 is a T6 platform, so it has a 5" exhaust outlet...I figured why choke it down?! so from that turbo all the way to the tailpipe is all 5"
also you should ditch that K&N filter. One of the worst filters you can run on a turbo diesel...these trucks when tuned suck way too hard on the filter which essentially sucks all of the oil off of them.
