Hi.I'm new to this forum so I apologize in advance if i posted in wrong section.
First,here is little history about my car.I bought this car with camshaft wearing through lifters already and EGR was blocked of with a plate (valve is still in the intake).So after replacement of the camshaft,lifters,timing belt and water pump I found out that vacuum actuator at the turbo wasn't working when vacuum aplied.Since those actuators have a sensors also they are kind of pricey and I had one from ALH laying around I sent my maps for remap and disabled need for that sensor,also they did EGR delete and tuned up my power little bit.So after all this been done,I drove around and got P0101 -MAF -Implausible signal.I replaced air filter,clean all grounds and finally after light coming again I did some logging and I thought that was a bad MAF so I replaced it with Napa rebuilt one but again light came back with a same code.I logged it again and again getting same values as with old MAF.Here is a graph from that log.I see my boost is little spikey but eventually levels off with requested boost but my MAF seems to drop down and then go back up

I would like to know if this could be another faulty MAF or i have some other issues .
Thanks
