There's a benefit to re-mapping the ECU if significant changes have been made to the vehicle's air intake system and/or exhaust . What this really does, is adjust the ECU's air/fuel parameters to deal with the heightened ratios . Short of that, one would be hard pressed to notice any significant changes in performance on an unaltered engine .
