I went back today and checked all of my wiring and I don't know how but its rite. and I was going to check to see if they were any codes but when I cut the key on to the code reader its says key not on . but anyways I remember reading somewhere about how to check for a bad maf sensor so I unhooked the wire to the maf sensor and dam if it didn't go to running rite like its supposed too. so I don't know ifs its bad or not I am going to ask the man who tuned my ecm if maybe he has it set to run without the maf system . and as far as the fuel pressure being at 65 to 70 its running ok with it as that I am going later and get another fuel pressure gauge and try it .thanks to everyone who responded to my problem .
