How are you tuning? Do you have timing control?

I have those pistons and never even came close to getting knock on the stock timing and fuel maps at stock air flow levels. Hell, you can get away with adding timing or boost or leaning out the stock fuel and still not get knock on 93. Not all at the same time though lol.

I run 93 as well.

With a good tune and proper boost control you should be fine.

I have a 1G with 9.0:1 Wiseco's that currently has 46,257 miles on it, with no troubles.

9:1 is what I would run, better offboost.

As everyone is saying with link or some way to control timing, you're just fine. The 2g timign map is very conservative. You'll be ok taking out or adding 1 degree here and there with that compression ratio. It's not at all that high. . .
