it pegs his 4000 psi gauge with 400cc injectors. with i think 150s, maybe larger.

has anyone got the guages figured out with tuning?

 

[Pizza pig]

monitor icp voltage through the obd2 port, thats what I do.

what is 4000psi in terms of voltage?

If the truck is tuned and HPO psi is off, wouldn't the voltage be off too? Or, is that the only case for some trucks, maybe 03-04s?

i've never personally checked, but I know on 05+ trucks the voltage still reads normal, just the pressure is different. Also can depend on the device being used to monitor. I've seen tuned 03-04 trucks read proper voltage on ids, and snap on stuff. Ill have to see if I can get my gryphon in my buddies truck when he gets back into town to see if that will read it correctly.

Adam...some trucks will experience the same thing with the ICP voltage as with the HPOP psi...no matter what year. When mine is tuned....ICP voltage will not go any higher than 2.3v and HPOP psi will only go as high as 1520-1550 psi. When stock ICP voltage hits 4.7v and HPOP psi hits 3600+ psi. I talked to Eric about this and he says both the voltage and psi will act the same way when tuned on some trucks. Apparently mine is one of them.
