OK I'm running the ''90MP_ATX_3-Bar_Sw-Bst_+20.zip '' in my 90' turbo mini. The van had 87 octane in it, and I went out for a drive to get gas and put some high test in it. Well I'm running 10 PSI boost right now, no IC. So I'm driving around, and with partial throttle it goes to the 10 PSI and started to miss and carry on a little bit, but WOT made it go away. Then after I put the high test in it didn't do it anymore. I never got the CEL flashing. Could it be something other than knock?
