Help on tuning 30 LB injectors in my 5.0

[pierce.nathan]

First off I have no experience on tuning vehicles when it involves upgraded fuel injectors. My mustang contains the following:

185cc intake 70cc exhaust aluminum cylinder heads
cold air
75mm throttle body
bbk ssi intake manifold
E303 Cam
1.7 roller rockers
255 lph pump
35-70 psi adjustable fuel regulator
30 lb injectors

I don't know if the 30 lb fuel injectors are too much, but I thought that I might be able to just lower the fuel regulator to lessen the injectors. Any information would help. thanks

Get a calibrated MAF or tune the ecu with a chip.

You won't correct for 30's with the fuel pressure....

I have a BBK 76mm MAF which is calibrated for cold air and 30 lb injectors. Is that really all I have to do? What should I set the fuel regulator to? I know that at stock for my car, they are set to 39psi

Yep, set it to 39psi.
You shouldn't have to change it...

If you can get the air/fuel checked with a wideband just to make sure the calibration is good on the meter , they are not always 100 percent perfect out of the box
