Does anyone have logs of running high Oct gas with the X-chip???

I didn't keep them, but a sizeable increase in timing was the most notable result

How high? My pic poster has some logs with 93 octane.

And most of the logs in my pp are with 94 octane. Is that high enough?

There are some in the archives. I remember searching once.

DarinS4Turbo's pic poster would be a good place to search. He usually logs with a 96-98 octane mix.

Where I live, we Have 94 oct at the pump and with some Xylene will be around 96, is it worth it???

I have only run 100 oct in my car once and I really didn't feel a difference. Maybe I didn't get a good brand or something, but I don't know if it is worth trying again. I've never tried mixing with toulene(sp?) or xylene before, but others seem to have great results.

*edit*

either with 100 octane gas or by adding toluene to my 91 craptane. VAG logs show a noticable increase in timing advancement and I find the boost levels to be more steady and don't taper as quickly as compared to when with 91 octane. I can't find the logs though...
