I don't see why we want to use octane booster of any description. tune the car properly and leave it alone. tuning on 99ron (and maybe even booster in there as well) then struggling to get 99 so banging in 97 and octane booster is not the way to go. tune on 98 with NO knock. even if you run 97 the ecu will cope easily and filling with 99 you will have a comfort factor re DET.
that car is deffo been detting, wonder how the pistons look?? Very lucky if the tips have not scored the bore but looking at them I guess they were so hot they more or less disintegrated.
getting every last bhp out of a car is not always the smart thing. Running 1 degree less advance you will lose around 10bhp but could well save your engine.
I have never used and never will use any type of booster. I would far rather run less advent and have a safe engine. never had a failure yet and been doing this a very long time.
Scary stuff all the same
PS that statement above got to be the kiss of death for the RS

The car which I was on about went back to MRC after getting a new charge cooler fitted, it was misfiring and thought the spark plugs were the problem but upon the re-map they discovered that piston 4 had melted! No case damage thankfully but now getting a re-build from forge due to warranty being void.
That's not good. I guess that's what happens when you want every last bit of power. I run mine really rich at the top end and do logs until I am happy. I like a bit of smoke ( unburnt fuel) keeps things cool, it wastes power but saves the engine.
Who's fault is it though? MRC? Or customer running additives and / or 95 Ron and nailing it?? Who knows.
I see a well known tuner getting nailed on FB just now as RS3 are killing pistons and rings, again who is at fault??
Tuning always carries a risk
BMW 540i
2018 GTR
F90 M5
X3MC
RS3 Saloon
RS7 FL best car I've owned. No faith in turbo oil screen (turbos failing) or sticking oil scraper ring causing missfires.
F10 M5 LCI still no rear grip lol
S7 black Edition Too big and heavy
S3 8V FL DSG 310ps, road noise is a joke
RS3 8P Rubbish
C7 RS6 Fantastic car but missed playing
GTR R35 800bhp, too extreme, crazy fast though
911 Turbo Remapped. Hated it
F10 M5, awesome but no rear grip
RS6 V10 700BHP crazy
Porsche Cayenne Turbo S 600bhp
