440cc injectors, Pro series fuel rail , B&M Adjustable FPR , gauge is dead on.

Motors around 11.8~12.0CR all motor build its street tuned right now but i had a question to what fuel pressure you guys suggest i just was throwing this in the air.

At idle its around 45psi with vacline on, during WOT it bumps to around 48ish or so.. suggestions?

 

Whatever it was tuned with. I like 50 psi @ no vacume. Not sure why, just seems to have good responce there.

Thx done so
What do you suggest i unplug the vac line and plug that line in the back of the pX manifold?

 

?

 

By no vacume I was refering to WOT. Set it with the vac. line pluged, then hook it up for idle. 40-45 is good for idle, or what ever you get, tune it there.

 

k making sure

Thx again donf, whats your thoughts on running it without a vac line any reason to keep the vac line on?

 

Better idle control, off throttle responce. No reason not to have it.

 

Thx again
