Hey this is prob a stupid questions but i have a sct 2 handheld controller for my car and i was wondering is it better for your intake to be richer or leaner for better performance?? please get back to me asap anybody

 

From what I understand, leaner. I have a Diabalo tune and my mechanic said the tune made the mixture leaner. I get great gas mileage and performance.

 

I'd suggest taking your car to a shop that will dyno tune it for you.

Let those who know how lean is safe without spark knock.
