ok my cars been parked for a lil so i filled it up w/ premium today because of the turbo install but there was prolly a little under a third of a lower octane gas in it, so the questoin should i retard or advance the timing and more or less because of the lowerd octane in there??

 

advancing your timing would be bad.
however if your not boosting alot, you maybe fine with the deluted fuel.

 

im sure your not driving directly to the dyno. so you wont be boosting much until it gets tuned right? then i wouldnt worry about it

 

sorry lemmie rephrase the question, im running uberdata, the usual basemap ignition retard is anywheere from like .75-1, so on that scale, which side should i tilt toward for haveing a lower valued octane fuel
