If I install a supercharger and then have to drive it 4 hours to the nearest tune shop to make sure it's tuned OK, will I be able to avoid detonation (in the event the initial tuning is not quite right) by not pushing the engine too hard, or is it to risky to drive it that far even at moderate revs?

Thanks.

Yields Water/Methanol 80%/20% mixture. Lasts me about 2 tanks of gas before the warning light comes on. Able to run 91 during PHX heat without detonation. I'm currently running an Aquamist setup.
