In General---
As long as you have not icreased the compression is there no use of racing fule if you don do a significant igition advance.

I would think that since you have the VEC2 and a supercharger (hence higher compression) you can program a more aggressive ignition curve (I assume) with the higher octane that might add some power.

I'd speak with Sean for more details....

You'll burn out your O2 sensers using leaded fuel, don't use 110

I agree that if the program for the Supercharger is programmed for the higher octane it would help.

I guess you could always put it in and see if it feels any different.

In the Porsche 993TT the factory computer will attempt to determine what the octane of the gas is and adjust the program accordingly. The effect you might say is "digital". You either have the advanced program or you don't. In a case such as that, the fuel makes a big difference. The effect does not feel linear you either have it or you don't.

He said the 110 is unleaded. With 110 you should be able to run a 0 degree card (pulling no timing out) and if you have the updated vec2 you could even start advancing the timing. timing = power.
