Bad MAF ??

[youngblood]

Got a question for everyone. I installed my front mount this week and went to go for a test run after it was done but forgot to tighten one of the clamps which blew off under psi.(off course).After that the car won't run good and my scanmaster keeps giving me codes 33,34 bad maf. I reset the ecm, took it iff cleaned it up. When you start the car it runs real rough then the service engine soon light comes on, and the motor runs fine at idle and if your just reving it , but soon as you go for a ride or try to build boost under load it hesitates ans studers real bad. my set up is stock chip, 3" maf pipe 9" k&n, front mount(custom),hooker exhaust , walbro pump,stock inj. adj. fuel reg. set at 42psi when vac. off. i have 50 # msd, and pt-61, 3" dp hks wastegate to go on but not untill i get this fixed. next ? should i replace it with a stock one again or go to 3.5 ls1 maf? if so what do i need to complete this change over. Thanks for any help on this matter.
