So i remember back on 2. 1 I could change conservative or powersave. 2.2 now and with chevy ulv 1ghz on bb . 2.1 i only get performance and on demand and user. Is it the kernal or something else i need to learn to make this happen? or not possible? I would like to do 1ghz on conservative or even run 700 with the same profile. On demand seems way too much like performance.
