Those with Quads' rail pressure guage
Can you tell me what pressures you are seeing? I'm seeing 4200psi at idle in park and 4800 in drive at idle/brake on. Problem is my Diablo is showing around 3000psi higher at both points. And this is with XZT bypass installed and stock program on Diablo. Same pressures and differences with XZT on and Diablo on Extreme, Tow or Performance....???
What the heck is going on?

this may or may not be something but...
when I was playing with my scan tool I noticed on the list of sensors I could read, there was a "High pressure common rail pressure" that I could read and a "fuel pressure sensor" that I could read and the fuel pressure sensor reads lower then what the HPCRP showed by about 1-2kpsi IIRC
I thought it was kinda weird
my point is I wounder if you are reading the two different sensors???
maybe quads reads one and the Diablo reads the other?????
does that make sense?

I miss read the title
so you guys know I don't have a quad rail gauge........
my readings are from my scan tool, not just a pocket reader either...its a in depth reader....reads every sensor on the truck.

Truck starts and runs very strong. I haven't gone WOT since the install because of heavy traffic. Maybe tonite I'll take her out on the highway and blow some soot out of the tailpipe. I did see 21-22,000 but this wasn't WOT... maybe 3/4 throttle and 50mph or so...
53 ******, thanks for the info on the two readings... I'll check to see if my diablo has that as well. What is the name of the scan tool you're using??? Sounds cool.

DTR's 'Go to Guy'
I brought my DRBIII home from work this weekend, I'll try to compare the readings of the rail pressure guage to commander later. I'll do it on stock and all the levels for a good comparison.

mine has the Chrysler expansion software, witch you would need to read both pressures......
you can read one of the rail pressures with just the basic scan tool..but not both.
