Do you think that running the PWM Meth / Procede combo will allow the car 's fuel to be downgraded from say 94 octane to 91 octane with no downside?
From the answers in this thread, the answer would appear to be "Yes." The only potential issue I see would be if the engine was not able to fully advance timing under cruise conditions with the 91, since the meth wouldn't be flowing.
Or would it??
Can your PWM meth kit be programmed to inject under lighter load conditions if there is knock retard, or if the IATs get too high?
