interesting 93 is typically pretty decent, possibly a bad batch. The hot weather we had recently could also have contributed. Not a ton of stock RS logs to reference to know exactly what to expect for avg ign and no one ever posts logs with that parameter either, I just know you should try to stay under 6 or turn the boost down. as adding more boost with such low timing isn't really making that much more power at that point and adding extra risk. but regardless that is still the cause of the boost "surging" is the AVG IGN changes mid map in those spots.thanks, yeah im on 93 octane. ill make map 6 and see how it does. i haven't had this "Surging" in the couple of years ive been running JB4 so could be bad gas. i try to only use gas from "name brand" stations but i dont think one was around the last time i filled up.
Get some known good gas, and now the weather has cooled off a little, give it some time to relearn and see what happens. custom map 6 is always recommended regardless though especially for RS.
