I religiously use these in my stage to the moon r58 icw that's running 30psi with big turbo and full bolt ons. These absolutely change my afr ratios too !

My Nissan only likes 89 or higher octane. It "shudders " at stop lights with 87 octane.Ifollowed the instructions. I added 2 tablets for a an 18 gallon tank. The vehicle still "shudders" at the stoplights.Hopefully it breaks down in the tank as advertised and it doesn't cause issues with my fuel filter or pump.

Set up a little test before I put these pellets in my gas tank. I put them in glass jars with about 4oz of 89 octane gas to see how long it takes to dissolve. Out of 5 jars with 2 tablets in each jar the quickest to dissolve was 18 hours! The last one was 24 hours.
