At last - my evo is fully upgraded . My tuner is asking me what fuels to use. Since he will do two maps, my first map will be based on 95 pump fuel. I'm not so sure about my second map.

c16 is my first option; however, many people say it will quickly burn my oxygen sensors. Is this true?

My tuner also dropped my rev. limit to 7,200 rpm because of the 2.3 strocker kit. Is this an extra precautionary measure, or is it a must?
