I've got my tune pretty much dialed in using Renegade 120+ race gas..

Now my supplier has changed from a Renegade dealer to a VP dealer.. So I just purchased a few cans of C16..

Will I need to change my fuel delivery to maintain the same A/F ratio ??

This is on a race only, max effort turbo setup..

Also.. Will I need to flush my fuel system of Renegade fuel, before switching to VP ??

Haven't made that switch personally; but looking at the specs of both fuels; C16 will want to be a little richer (14.7 vs 15.0 stoich) so adding a bit of fuel certainly won't hurt. Bearing in mind boosted stuff is usually living on the richer side anyway. The C16 is a bit heavier; and has a pretty low RVP so you might find you need a little bit more ignition timing to get back to where you were on the Renegade.
