hey guys well just got back from my trip car ran well just noticed when I hammered on it it pinnged under boost Im running super fuel and just changed plugs wires all that good stuff running 180 stat I thought I read a thread once about being able to adjust timing anyway any suggestions?
 
did this happen after you fueled up at one place or more than one place....I got high octane once that pinged bad under boost ran it about half empty and went to the local small airport and filled up pinging went away...I think somehow ...cant prove it....I was sold 87 by mistake sure ran like it...

I second the fuel thing. I used to identify all the bad gas stations with my 93SC. They were allways the ones with just one hose and you had to choose the grade of gas to come out of it. From then on I only went to the stations with a hose for each grade of gas. This wouldnt stop a really crooked station from doing something shady, but it did stop my pinging...
