Iv noticed that since I have changed the Maff the car will only boost to 0.8 and not 1 bar and when I fitted the homefry Ecu it only boosted to 1 bar and not 1.4. It doesn't feel aggressive it's more of a smooth acceleration. The Maff I have fitted is a brand new one from Audi, there are no boost leaks as they have all been sorted and all the coils are new. Just wondering if there any other reasons why it feels Dull.

Check the female pins on the Mass Air Flow (MAF, not Maff) sensor harness connector. Sometimes they get pushed back in the harness and don't make full contact with the fixed MAF male pins.

just done a vcds check on the car and it threw up th codes above with the homfry ecu. I then changed back to the oem one and no codes were present. The homfry ecu is producing 0.9 boost and oem one 0.7 max don't quite understand whats going on here. Would a boost a small boost leak be the cause of the lack in boost.Comment
