redline S1? Same as mazda's Stuff?? https://www.nopistons.com/forums/pub...IR#>/blink.png

are you having any problems with your injectors? Running cleaner through them will almost never enhance performance, but it will open a completely clogged injector if you redline it a couple times.

should i be running 93 octane in my TII? i've always been running 89 since i got it last summer.

No Im not having performance problems, I just got it so I want to clean it up as much as possible.

If I were you I would definatley run 93. Especiallly with those mods done without andy fuel mods. Better to be safe then sorry. About the injector cleaner I usually run a bottle or 2 a year with out any problems.
