Does anyone have any experience using octane booster to stop knock and get the IAM up? I'm running on 98 petrol, it still knocks and the IAM is very very low and it pulls all the timing out. Wondering about using some octane booster to see if raising the octane will stop it knocking and bring the IAM up?
What brand octane booster did you use?
Did you mix it as per the instructions or some other ratio?
