umm, hate to be the bearer of bad news, but those tablets only increase the octane 10 points not 10 octane. There are 10 points per octane so biggest increase with 2 tablets is 1.7 octane.

There are much better octane boosters available, such as:

Millers Oils up to 4 octane (40point) increase

Lucas Oil Products (UK) - Heavy Duty & High Performance Lubricants up to 4 octane (40point) increase

Nitrous Formula - Black up to 6 octane (60point) increase

I know the Lucas stuff works well as thats what I've been running for close to 2 years with no problems. Made 292bhp on the rollers last time on a completely standard WRX RA with no remap.
