IF you set your gauge to go off at 1-2* KR, your gonna see an awful lot of red.. I had my aeroforce on 4* on my ssei, as it was a # That many thought was a good point to start watching what your doing.. Also The higher the RPM and boost the worse it is.. ex 2* kr will not be as damaging at 3000 rpm, and 4 psi, as opposed to 6000 rpm and 10+ psi
