Ok i tested my fuel presure while driving, Just crusing at speed at like 60 mph its about 38..

When i had it floored up to 70PMH it stay at 42-44psi the whole time.

One time when i was stoping from 60pmh to a stop at around 45mph its starte to drop way low to 35 then to 30 then to about 22psi, but as soon as i got on the gas again it went right back up to around 38-40ish.
