Message Have you got a custom tune for your setup? You might find that on 94 octane, you might be able to run more boost on just the pump fuel.

I noticed you have 530BB turbos, and both comparisons I mention below are running the same turbo.

I have a high compression setup and I am running about 17 psi on 94 octane. Of course, I do have cams that have been adjusted which helps (prior to this, the most boost I could run with my 500 cams without adjustment was 15 psi.

Vorpalz just had his car tuned this spring (stock compression, 400+ cams that were adjusted on the dyno). He is running 19 psi of boost on pump 94.

If all you really want is safety, I wouldn't go water methanol injection. Your best bet would be to go with a J&S Safeguard.
