I always use 93 fuel , it was just off hard excell but now with block offs it does it all the time and it sounds like a shotgun going off all the time , kind of annoying . I'm not sure if what I'm changeing with the timing is deg or % , cuz the fuel is % , + with it being the 929 idk what's a good place to set things

 

well, fill up your tank with reg - not 93. that will help. run a zero map.

 

Thanks for the tips
