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?

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 got the fuel delivery code three time all three resulted in bad injectors. does the predator add fuel pressure?

Does the extreme run more or less fuel pressure than the standard puck? Seems that every time i pull with the puck on,both in the 60 and 90 settings I throw a fuel rail pressure codes. Maybe if the extreme runs less pressure I could use it to pull with..

what is the difference between the normal puck and the extreme besides the boost fooling? are there any horsepower diff? i like the nob instead of the micro switch seems much stronger. thanks for any input

had same problem with mine all of a sudden, took it to the shop and #1 injector was bad. replaced injector and it runs smooth again, well as smooth as a diesel can. i guess in 06 injectors were a common problem

thanks that worked, but now it says there are no parameters to motify with this truck . what happened to tire size and speed limiter?

i also have the same problem. i had my truck in the shop they reflashed my computer and now when i go to install the predator it say vehicle is not in database my cal.id is 35325833ah can we get some help

where u checking the faults with your predator? if so sometimes the programmer would not read the codes i had to hook up a star scan to find out what codes i threw.

thanks for info. i was concerned didnt want to pay for next set if it was the predator

so even if i run the preadtor alone it still adds pressure?

mine never idled rough, i found out that the predator would read multipule codes though, when the injector went it thrwe two codes and the predator read them

maybe instead of bashing diablo about 1 or 2 mpg ,we should get together to bash the fuel companies charging us 4.00+ for a gallon of diesel . i dont think mpg were as much of a concern when diesel prices were around 1.00 and that wasnt to long ago

had a injector fail yesterday maybe thats y I kept getting codes. didnt throw them when it was in the stock tune though. hopefully i will get more info to shed light on this subject!!

does the predator boost fuel pressure or does the puck? the reason i ask is because on a short trip on highway yesterday i had a injector fail and fill crank case with fuel. i was in extreme stack tune with the puck off. any info would help?
