Ive been out doing some logs today and pretty sure i've got an old MAF thats on it's last legs. MAP seems to be fine so i assume that shows that shows its the MAF sensor thats gone. Can I have your opinions please guys. Pretty sure i need a new MAF but just checking. Is there any maf i can buy other than a genuine pierburg one?

Heres some graphs logged in 4th gear up a nice steep hill both logged against RPM
