I'm installing a vortech on my buddies 88 GTA this week and we are installing an AFPR, shorty headers, and runners at the same time....my stupid question of the day is this:

What do you run your fuel pressure at??

I haven't looked under the TPI in a while, can I set it running or do you set it with the engine off, key on.?

Thanks in advance.

If you set your fuel pressure around 45-48 psi or so, the FMU should take care of the rest.

EDIT:
You can set the pressure with the car running but you will have to remove the vacuum line that runs to the regulator. This will throw your pressure setting off a hair but if you verify pressure WITH THE VACUUM LINE ON then you should be fine.

Good luck!
