92-90 ok I am stationed in anchorage AK but I am deployed to afghanistan. I just bought the zo6 in my sig. It is on 10 lbs of boost. now here is my problem. it is tuned for 92 octane. This is fine exept that Alaska is retarded and they dont have 92 just 90. I have just played with hp tuners. I dont have a lot of experience. how much timing would I have to pull and what other tables would I have to change?

The low octane table should save you as long as your tune/r has not copied and pasted the high octane table to the low. You can take about 2 degrees out of the high and possibly 3 or 4 out of the low to keep you in a safer range, but honestly the car should be driven and re-dynod to verify the max spark you should use for that octane of fuel.
