Car is running out of fuel, need alot of help! ok i have a 233/239 cam in my car along with the normal bolt ons, my complete fuel system is stock..i dropped my car off to be dyno tuned today and later on they give me a call and say something is wrong with my car..when they went to dyno it the hammered on it and it went extremely lean..they hooked up a fuel pressure gauge and they said when they hammered it the pressure would drop like a ****** rock 
..they tried a new fuel filter and that didnt help ****..the injectors are fine and there are no clogs in any of the fuel lines..so i told them to stick a walbro fuel pump in and try that..we dont know what the hell else it could be..my car only has 10,000 miles on it..so what else could it be? they are gonna change out the pump tomorrow and test it..i will keep yall update...what else could it ****** be? also my car is out of warranty so thats why i went with the walbro pump..and i would have posted this in the fuel section but that place is always dead...thanks

I will state up front that I don't know enough about it but if your injectors go to 100% duty at WOT isn't the fuel pressure going to drop? You say it drops like a rock but what specifically does it go from - to?
