Notice to all employees.
Due to lack of funding we are forced to turn off the light at the end of the tunnel.
or how about a 2200, and would a regular fuel pressure gauge be fine to see what fuel pressure the car is running at? <br>

I too would like to know this, it will help once my setup is complete.....
I got an 04 ecotec and im running a 100 shot wet kit with only new plugs nothing else and it was fine.
KOEO 345-414kpa (50-60psi) I will check at idle and at WOT. Soon . 04 2.2 eco.
Ok i put in my Autometer Fuel PRessure guage the other day on my ecotec... When the stock FPR has vacum (at idle only when the throttle plate is closed) the ecotec gets 50psi.
When you are on the gas it gets 60psi.
So ecotecs run 60psi static, my car is a 04 with 30,000 miles. I also put in a FMU so my FP rises to about 65-70psi under boost. Reason im posting is because im going to be the guinnee pig for Ecotecs running Boost AND nitrous. (6psi and 35-50 wet shot)
Keep it safe, keep it rich.

on nitrous kits isnt there a fuel pressure cut off switch? I could've sworn there was...if so then how could this be an issue?
Also couldn't this be avoided as well by just running a wet nitrous kit on an engine that isn't worn?

see, this sounds good, and not too high. when i had my 91 3.1 z24, idle psi was MIN IMUM 38 psi! (techs said).i was working at a gm dealership and the techs said they would like to see 50 psi WOT, instead of the 43 psi i was getting......along with a signifigant bog. ok, like 10+ yrs ago 40 psi wasnt even necessarily high enuff. just food for thought...

bump bump ?? if i get an autometer fuel pressure guage would tha tbe cool? do you check your fuel pressure everytime you spray? or is it a one time thing??
i like my nitrous like i like my women, wet!!
fully built 2200-TO4E T3/T4-HP tuners-373hp @18psi
okay so what would be the ideal fuel pressure for a 2.4 lets say a 25 shot and a 100 shot? what should i adjust it too?
I have a 05 cav and I put about a 90hp shot of nitrous. It had 2 good runs and on the 3rd one I blew the top off of my number 2 cycl. I popped the hood and noticed that the hose from the fuel pressure reg to the nmu (nitrous management unit) had came off. so I was way too lean and stuff got hot and broke. But to my understanding at wot the fuel pressure reg is at 0 vacc anyway so what dose the nmu do to the fuel press reg.

are you sure this is right..
i got a 04 eco sunfire..
i'm measure the preasure at the rubber line in the back... vs ... ??? where you did it???
at idle im at 62-64 and at WOT.. it pretty much stays the same..
THATS STOCK!!!
now is that completly wrong.. or is my gauge/ sensor bad?
running a glowshift fuel preasure gauge..
nittrous is my next step on my build..... also
dry shot is trough the intake and wet is through the injectors? or is it the otherway around...????

Yes thats correct dry is thru the intake and wet is thru the injectors
uh... what? Please dont give advice. Dry nitrous systems (
) only inject nitrous and use the injectors to add more fuel in one way or another. Wet nitrous systems (
) supply fuel and nitrous seperate from the factory injectors ....
Remember... One test is worth a thousand expert opinions.
