What kind of difference would I see from 91 to 103 gas?

Hum, there is a gas station next to my house that has 103 gas( but its like $5/g) I want to know what kind of gain would I get. P.S. I dont have a AFC yet.

nothing.

less power

the higher octain fuel is to help with detonation from higher boost or higher compression levels. you may not notice it but it will help out when you raise boost to higher levels. I add a few gallons of 110 on race days.

You'll see no gain unless you up the boost. The higher octane will actually bring down power just a bit.

boosting 9psi i lost power

it would take a few more cranks to get your car started...

the slowness is made up for by the weight reduction in your wallet.

hahaha, its not worth doing unless you can tune for it. the higher octane rating will prevent pre-ignition but it will also not combust at the correct time unless you adjust your ignition timing to compensate for the delay. you don't need it.

Remember, there is no enchanted liquid pixie drink that will magically produce more power on its own.
