buy only c.a.r.b. certified headers,chips, etc. and make sure your mixture stays somewhat lean.How do you improve performance with a truck that has california emissions?
Mostly. The mixture must stay controlled, which does generally mean slightly lean -- but switching back and forth to slightly rich. If you make a lean mixture all the time, your engine might detonate and you'll have high NOx emissions.buy only c.a.r.b. certified headers,chips, etc. and make sure your mixture stays somewhat lean.
