just wanted to know because had a problem with my car a while back with it bogging down going into boost but now that it's fixed am getting light detnation
and my af guage is on the rich side.am not running a wideband o2 because am trying to get a egt gauge instead.so i was thinking that the 93 octane gas that am using my not be high enough so i was thinking turbo blue so the light detnation that am getting will go away.what do you guys think is this a bad move on my part?
