Just wanted to post some of my observations with the Predator and my new rail pressure guage..
Idling it hovers around the 900psi mark no matter which tune I am running. On the Regular Extreme tune the RP goes no higher than 23500psi.
Regular Extreme tune along with the Puck on the low setting and it reaches around 26500psi.
Today I loaded the Extreme RKL Stacker tune and w/ the Puck on the 50hp setting I was well over 27000psi!! Man the truck runs awesome on the RKL tunes but ouch on that high pressure! I haven't tried the non-stacker RKL yet but I'm sure it's up there too...
That's all I have to report except that this RP guage is cool.

You mean idles a 9000 psi???? remember X 10

That is something weird with downloaders. It seems like every one of them jumps up idle psi about 1500-2000 psi???

Could you post some pressure numbers for just the power puck? I would like to see how much pressure it adds on both settings.

Dodgezilla

Ha Ha!! Yes, I meant 9000psi. I keep forgetting to add that 0 to the number......
The only bad thing I could say about this guage so far is that where I mounted it right above the steering wheel you can't always see the readout due to the sunglare on it. Other than that it's a great piece....

Dodgezilla

I'll do that. It just takes forever to change settings on the Predator. My numbers may be a bit skewed due to running a bigger turbo though. If anything I would think my numbers would be higher than a truck with a stock turbo....

Dodgezilla

I took the Predator off and with the puck only it still gets up over 26000psi. idle pressure dropped down to 7000psi though. The truck sure is a dog though compared to when the Predator was on it.....

So extreme tunes are pretty safe, rail pressure-wise, w/o the puk, right?

Thanx for the info Dodgezilla. You know I am waiting for my tuner like crazy.

The Extreme tunes, even the RKLs, seem fine as far as rail pressure goes. It's that Puck that seems to be adding all the pressure.....
