MAF plugged in or out? cant find 100% answer!!!!

[jackoni]

Sorry if this is covered but when i search through the threads people have different answers.

I am having boost issues with my 180 Cupra
Severe lack of low down torque...used to boost hard at about 2500-2800 and now more like 3100-3400

I have owned my car for over 3 years/30k and never changed a MAF so could be my fault but i cannot find a definitive answer...

When i disconnect my MAF my car runs the same only for slight idle rev change.

Should it be running better or worse disconnected and my car running the same mean the MAF could br faulty?


no codes stored

Thank you

Boost issues, probably vacuum leaks or n75 related
