Sorry your right, I just made it up for the sake of a good story. Pffftttt Well my car(s) did run like pig(s) on v power but I have spoken to several people with wrx's and they've said the same thing. As for my white car she loved that stupid green sh*t at united with lower octane coz fowler is the sh*ttest tuner ever!!! Lol everyone's experiences vary, I dot use it coz I have had no positive experiences with it all negative. At the end of the day it's what engine runs better with is what you pick. For some that might be shell, for others it may not.
