Not a good idea. Plus, timing is something that almost always needs to be adjusted between setups. Lot's of things determine what optimum timing should be. Mileage on the engine is one. Using a tune built for a specific setup (and that person being an enthusiast), and then going down in octane on top of that isn't good.

do one or two pulls. if it pulls more than 10 degrees timing, it isn't really safe.

Not only that, it won't be making the power it should
