Run one or the other. Don't do half and half. Run the tank low, fill up with the opposite and switch to that fuels tune.

You'll want to change your fuel filter a time or two afterwards.
With a stock pulley you could probably run it without tuning if you took it easy for the first few miles. would need to keep an eye on wide open stuff, tuning would help alot.
