Does the predator increase fuel pressure??? I have had two #1 injectors go bad and it seems that another just went bad. I need to figure this out any help would be good

I believe just the Puc adds the pressure, you really need to watch your rail pressure, its the added fuel that makes things hot and hard on the injectors..

I didn't have the puck on and i was run in the performance mode. The injector I think is leaking from the top because it fills my crank case with fuel. Is there a gauge I can by to monitor rail pressure and how much pressure is too much?

You didn't have the puc "on", you mean not plugged in or the switch in the middle position? If it was plugged in on the middle positon its "on" at the lowest setting. Yes there are plenty of types of rail pressure gauges available its your choice, Dodgezilla on this site will tell about what the rail pressure can reach with the Predator...

Rail pressure on my 07 was NEVER even close to being an issue when I was only running the Predator even on the Extreme RKL tune. Maybe 23000-24000psi. Now, when I added the Puck into the mix then RP went way up to over 26-27000psi. Actually, if I remember correctly, the puck would raise the RP pretty high on it's own.
I'm not sure if the Predator adds any pressure but I know that pretty much all of the others don't and that's why you can stack them with a pressure box with no problem. I "think" the Predator is like that.
Modding these trucks will push stock parts to the limit so you may want to consider some better injectors if you keep having the same problem....

what he just said ^^^^ upgrade to 50 hp injectors , sounds like your burning up the stocks ones.

What are the signs of a cracked or bad injector?

hard starting, no starting, there may be other symptoms as well.

heard of fuel getting in the oil, also white smoke.
