5.4 Base fuel pressure (differential)
The recommended base fuel is 90PSI, 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 90PSI or desired pressure, making sure
to have a stable number
IMPORTANT
It’s not recommended use more than 140PSI of differential fuel
pressure, this will damage the injectors
