injectors
I have seen many dodge pickups with dr. performance packages on them. They say that they have had the injectors changed and that it provides more horsepower. Everyone of them I have seen has never had gauges or exhaust on the truck. They claim that with new high horsepower injectors that egt's are not going to climb. Does anyone know a little more about this?

I'm no expert but it seems that bigger injectors would deliver more fuel. That would mean higher EGT and possible engine damage. Many people get lucky, but a broken engine could cost thousands. Gauges are cheap insurance. I have no mods on my truck yet, but gauges will be first. There are lots of ways to get more power, but without the gauges, you won't know until it's too late,

Well, if you want bigger injectors then you better make sure you have $$$$$$$ and at a minimum, forged rods.
Add some swamps, a high output HPOP and an H2 Turbo or Garrett BB, reprogram your tune and you're good to go.

I agree, I just don't understand what they are meaning about the change of injectors and the egt's are not an issue

Given the low power output of a stock 12v, or early 24v Cummins, I would speculate that stage I or II injectors probably only brings their power output up around that of a stock PSD....so they may not have EGT issues, but without the telltale gauge to back them up, they're just talking smack.

I see a lot of guys worrying about EGT's as you should, I found 150-200 degrees of cooling power in my high flow manifolds I am pushing a ton of fuel through my truck and it used to get real hot now with these manifolds even pulling at the truck pulls I have never been over 1100 at the end of the pull they are expensive but one of the best investments to date www.paulshp.com
