#6264, "RE: 1.6bar boost spike w/K&N only?" In response to In response to 9
^^^^^^^If you are using the stock gauge that is on the gauge cluster, stop. It is garbage. I'm not sure if that's what you meant, but the stock "boost gauge" doesn't even read boost, it reads a combination of fairly random things and guesses boost based on that.
If that's not what you meant, then, my bad, but maybe the info will help others.
