    Brian at cams performance in darwen can give you options on brand choice on the sensor and also offer fitment I highly recommend him as a one stop shop you can’t go wrong
     
  3. If your having it mapped soon, then the mapper can bypass it so its not needed.

    I’m pretty sure you can’t knock/map out the first lambdA
    but second one yes you can

    rear sensor is the only one that can ne mapped out.

    id like to think it has been mapped with the above mods or it would drive like a pig

    do you have a boost gauge? whats it boost to?
