So i picked up an s3 just before christmas. Good price but noticeable low boost.
logged it a few times and it pinpointed MAF to me as the readings never got above 100.
bought a new bosch maf yesterday and it has made it a lot better but still not boosting as i expect.
had a run out for 5 mins with laptop plugged in today and here is my requested vs actual boost graph.
does this look like air leak or N75 valve?
near the end of the drive it started boosting really well as you can see so im puzzled.
engine was a brand new rebuild less than 10k ago along with a rebuilt turbo with receipts.
