So a week ago I get my SCT tuner and hook it up to my car. Ran it for a while on the 87 tune with no problems. Three days ago I put 93 octane in it so I can run the 93 tune. Then yesterday my service engine soon light came on. Checked the codes and they were p1000 and p0405. Cleared the codes and it drove about 2 miles before the SES light came on again. Is this from the 93 tune or is it just a coincidence?
If you can't beat them, Get a supercharger.
