Fuel Pressure

[eatsgmcar]

When the pressure was at 38 psi (# 24 injectors) the
car was very slow. When i was flooring at 2000 RPM
i could notice a kind of flute noise in the pipes like if
the explosion has never occur in a cylinder.

Also, as i said, i could easely notice a lot of "pop"
when releasing the gas pedal at the end of the 1/4 mile.

Now the car is running fine with 38 psi and #30 injectors.
The spark plugs are fine, no black smoke, never broke, good ET,
no strange noise only strange fuel set up.

Is there someone who can explain that?

MAF tube......... interested? HEHEHE
