Base fuel pressure (differential)
The recommended base fuel is 43.5PSI, this allows a better fuel atomization in the combustion chamber.
Execute the following steps to regulate it:
a.
Disconnect the fuel regulator vacuum hose
b.
Rev the engine up to 3000RPM steady
c.
Regulate the base fuel pressure at 43.5PSI or desired pressure, making sure to have a stable number
IMPORTANT
It's not recommended use more than 120PSI of differential fuel pressure, this will damage the injectors
