Garey for you, like Stephen has mentioned with his car, the 100 octane program really works well with the GT1's and Stage 2's.. As far as the 5bar I wouldn't add it unless you really needed the fuel. You would have to data log your AFR's to really know.

Yes, I recommend that you purchase the 100 octane program with the GT1 or Stage 2 turbo's.. Best HP bang for the buck..
You must purchase the Stage 3 programming, then add the switcher to get you the 100 octane program.
