Hey guys. I recently took delivery of my new Dbilas cai for my cupra. I am fairly impressed with the quality of the kit however my only real issue is that the MAF appears to sit too deep in the filter pipe whereas when fitted to the original airbox it sits dead central in the line of airflow.
Anyhow after i finished installing it i was intrigued to see if my airflow readings had increased (previously maxing out at 221g/s) but to my surprise i was seeing no more than 209 g/s. While i was out logging i had a quick look at my long term fuel trims which have since risen from -3.2% to +7% multiplicative which suggests the car is now running lean. Now my question is could this be due to the fuel pump maxing out or could it be down to the position that the MAF sensor is now seated not allowing it to get a true airflow reading?
Has anyone come accross this problem before after fitting a filter? Or any suggestions as to what else could be causing it?
