quote:You're living in the '70s. All modern engines have timing that is electronically constanstly changing to meet the load demands on the engine. Modified engines?...that's different, and too big a topic for most folks here. Yes, with the right mods and the right instrumentation changes can be made that help a lot. Most changes just cost a lot and help little--if at all. Ken
You can always adjust your ignition timing for more power with higher octane, some cars do it automatically.
