i had broken my pcv at the front of my valley cover replaced it and it works great now

I broke the pcv at the front of my blower and didnt notice it due to my excessively loud exhaust replaced the fitting now the truck is super rich at idle need to take some fueling out but its working

have found a problem the reason it leans out quickly on bank 1 the y pipe clamp has come loose and pulled the y pipe back off the header and the vacuum from the passanger side is slowly pulling it...

I'd say possible if the truck didn't fuel properly after it starts moving

I have tried this earlier it seems with the maf unplugged it fuels normally 104363

this truck has a 5.3l with a magnuson tvs 1900 kn cold air intake speed engineering long tubes mbrp catback but currently lean at idle just hoping someone can help me calibrate the maf or get it close
