A/f ? I installed a cold air/ram air intake from K&N, Last week. Before I did that I ran my car at the track and my A/F was like 11.9-12.2 now since I have installed this it is 10.8-11.2. My questions are is this commin? I'm assumming I need a new tune. My car has the street heat stage 2 cam with 241 heads stage 3 port job, UDP, headers 1 3/4, 3" tsp y-pipe, slp loud mouth exhaust 3", ls6 intake, pp tb,
The Cai likely leaned it out so your fuel trims are adding. If the trims are positive when you go wot they get added on top of commanded. You are right you need a tune to fix it.
