TUNING YOUR LS FOR POWER! WHAT WORKS? HOW MUCH TIMING SHOULD I RUN? WHAT A/F SHOULD I RUN? IS 13:1 TOO LEAN? IS 10:1 TOO RICH? HOW MUCH POWER DO I LOSE WHEN I RUN AN LS AT 11.0:1? WHAT HAPPENS IF I MISS MY TUNE? CHECK OUT THIS VIDEO WHERE I RAN A 5.3L ON THE DYNO EQUIPPED WITH A BTR RED HOT CAM. THE MOTOR WAS "TUNED" TO PROVIDE NEAR 13:1 A/F, THEN 12:1 A/F, THEN 11:1 A/F THEN 10:1 A/F. WHAT WAS THE DIFFERENCE IN POWER? I THEN "TUNED" THE IGNITION TIMING STARTING AT 29 DEGREES, THEN 24, THEN 20 AND FINALLY, 17 DEGREES. WHAT HAPPENED TO POWER.
