THIS MAY BE A STUPID QUESTION BUT, WHEN YOU HAVE A FUEL PRESSURE GAGE HOOKED UP SHOULDN'T YOUR PRESSURE IN INCREASE WHEN YOU GIVE IT GAS? MINE TENDS TO DROP DOWN TO HIGH 20'S.
No the pressure doesnt increase when you hit the throttle, if its decreasing very much it means your fuel pump isnt keeping up. I had that problem when i bought 30lb injectors and tried to run the stock pump, everytime i hit the gas the pressure would drop drastically!
