I personally run boostane on occasion. Going from 93 to 98oct yielded a gain of .30 secs on my 60-130 in similar conditions. Could likely drop another .3/4 secs if running on 100.

New update after a while, i changed the spark plugs whith stock gap , and did a service include oil and filters , also changed the airfilters , but still my car feels slower , also my 100-200 km/h is slower ,my best is 7.4 s' instead of 61-6.2s' 🤷
