Running V Power Racing 100 Octane Fuel In Engine Tuned For 98

[Russco]

anyone has info on boost 98 versus v power racing 100? which would result in a better gain after a retune?

Have mine tuned on v power racing and ran boost 98 thru it when I couldn't get the v power - to be honest you'd need a retune on Boost 98 to make a direct comparison but from running it in mine I found the vpower allowed 4psi more boost than the 98.

Does anyone have any numbers on how much power they gained because of adding a few degrees of timing? The reason I'm asking is that I have my car tuned for 98 octane and had to pull some timing out of my map as where I live I only have 95 available. I'm interested in how much a difference in rwkw this would actually make.
