what fuel pressure to run

[c mak]

I was just curious as to what fuel pressure everyone is running who is turbo'd? I have an adjustable fpr and running the dsm setup on an f22B.
thanks

Run the fuel pressure that the manufacturer of your injector recommends. Just make sure your injectors are correctly sized for your application and you're properly tuned.

In my case I got the OEM fuel rail machined to accept the DSM OEM FPR

do you know what the stock fuel pressure is for a dsm? I don't want to run too lean especially!!

if you have a 14b turbo, 450cc injectors and are running 8-9 lbs boost you want to tune with the injectors at 44psi for the 2.2L

Honestly, run the OEM regulator.. Youll be happy you did. I have run a few different ones on my accord, and noticed that with all of them, they are not accurate. One day it will be 50psi, the next day 35, then maybe 55 the next... Not worth the b.s.... You also have to remember this. If your OEM fuel pressure is 36psi with vacuum, and 43psi with 0 vacuum, at 10psi it will be 53psi, and at 20psi it will be 63psi....

i forgot to mention that you need to have 44psi with the vacuum lead disconnected
