+1 watch out for the additives, they can really fakk up sensors

for a proper comparison you would have to completely flush the engine / fuel tank and run the engine at speed pre dyno - all on the same day cos of all the variables

and obviously each and every dyno run is different, and has different results

just a waste of money imo

just get higher octane fuel - its a no brainer.
