    Default Astra j vxr running lean

    Hi guys so Iíve taken my Astra j vxr to the tuners and itís running lean. Itís got a airtec intercooler a double defatted full system boost pipes and an induction kit and cold air feed. I donít know much about cars as I bought it from the garage like this and this is what the tuner is saying to me any ideas?

    Get your Turner to remap the car

    you need to get that fixed before you lose a piston.

    A duff lambda sensor, a faulty MAF sensor or a bad map can cause lean conditions

    The lambda sensor is getting mapped off as it’s a straight thru pipe. It’s the evap that’s causing the problem and why it’s running lean he’s saying. Would this be the reason for loss of power? It still feels faster than standard but not where stage 3 should be.
