ill put a fuel pressure gauge on it tonight. as for the injectors i was told they were 24 lb injectors from the guy i bought the car from but he lied about stuff that was done to the car. they are orange injectors so i think they are 19 lb stockers. if they're stock, now i gotta change my signature

do you knwo what the MAF is calibrated to? is it stock still?

i believe the mass air sensor is stock.
i also did the trouble code thing and nothing resulted from that.

update
still cant find whats wrong with my stang. last night i took it out and drove it and i thought it felt like something was loose, like my flywheel or pressure plate. so i dropped the trans and nothing was loose, it was all still torqued to spec. i dont know of this will help but i can describe the vibration im feeling and hearing. it sounds and feels like the drive shaft has loosened up on the rear end while driving. but now its while driving and while parked.
also i dont have a fuel pressure gauge and my fuel pressure regulator is not adjustable. ill buy an adjustable one tonight just to eliminate that part. any suggestions on what kind i should buy?

i have the numbers on the fuel pressure.
when its idling its at 32 psi. and at 3000 rpm it drops to 30 psi. i dont know if this is the issue but its all i could find.

well, i finally figured out what was making my car vibrate. i found that the harmonic balancer had loosened up. it must have spun on the crank shaft because i couldnt get to tdc using the balancer as a guide. im getting a new balancer tomorrow, just in time for it to go in storage on saturday.
thanks guys for trying to help me find the problem.
