Fuel Pressure

[eatsgmcar]

My ET went from 13.30 @ 102 to 12.43 @ 108
when i raised up my fuel pressure from 38 psi to 67
psi with 2 psi increment each time. (# 24 injectors)

When it was at 38 psi i could heard a lot of small "pop"
coming out of the pipes as i was slowing down at the
end of the track. The car was also very inconsistent and
ran better when the engine was hot. I lost 2 thenth at
night compare to what the car did during the day. I think
that it was few symptoms telling me that my car was hungry.

Hope this help,
