I would doubt it with only 90,000 miles but you never know. Too bad you don't have an O2 sensor, you could get some feed back from they system on your mix. I think you may be right that the EHA tweak may be masking something but I have no clue what that may be. I'd say 300 miles per tank sounds decent so you are probably not far off on the mix. Do you know what the spark advance is on your engine, and have you replaced the plugs etc, and looked into the chance of a vacuum leak?
