Octane booster?

[dude496]

Well after alot of time and money spent, i finally got my car dialed in on 93 octane....SVT focus pump, 42# injectors, Flowmaster 44 mufflers (pretty sure thats what they are, sorry bought the car used) Procharger P-1SC, dyno tuned for the 93 octane.

I just moved to Oklahoma, and 93 octane is hard to find...i've been running 91 octane with whatever octane booster the gas station sells...i'm having alot of knocking anytime i go over 1/4 throttle....any recommendations on a good octane booster? Should i retune the car to 91? Or should i just search out the few stations that sell 93? Keep in mind, this car is my daily driver. Any help would be appreciated.

tune it for 91 octane, unless you garage it and its a weekend racer then just leave it tuned to 91, finding an octanebooster almost everday for your car will KILL your wallet.....

I agree with the above. Also, you dont really know what octane its actually at even with the boost.

Tune for 91 or risk teh engine.

If it's tuned for 93 and your using 91 + octane booster, your going to blow your motor. Even with 2 bottle of booster, your octane might only be 91.2 .

Don't drive the car if you can't afford to retune it for 91 octane. Or find 93 octane somehow.
