IF You think these cars are set up lean your totally wrong ! They actually run pig rich under hard throttle like 10.8 11.4. They get power out of these cars by adding timing and leaning fueling in certain areas 12.6-12.8 is where they tune NA cars like these for power and Force fed cars 11.6 11.7 are where my cars were at top rpm under loadDon’t threaten me with a good time
I am going to tune mine. Reading stuff about these engines has me just a little concerned. When I clock 15k miles or so and I’m not experiencing any of the so called issues with these motors I’ll get a canned tune.
Personally I think a tune improves reliability on modern engines. My theory is they are factory tuned to run lean as possible for emission reasons. But I am no engine builder so there is always that.
