I NEVER have a flat timing curve in my turbo cars. It's no coincidence that most poorly tuned turbo cars end up spitting out gaskets well before redline with a flat or stock timing curve...
That being said, you should be able to see about 21-22 degrees total on 93 octane with that combo, but good luck getting there with a flat "locked" curve.
