If you tune for a higher octane like that, you always need to run that level octane. That's why I tell guys not to add fuel oxygzers on tune day unless you plan to run it every day like that. Sure you'll get a higher number, but I dont like the risk Vs return if you dont run that adder every day because your traveling away from your favorate fuelling station
