You really should be able to get the same rpms with either; it’s just going to be easier and take much less time with pump gas. The tuning window is just broader. We can get above 10k with either, but it just takes more trial and error with race gas. When I wrote that we always get better performance with pump I really should have written we get better performance with much less tuning. Your carb tuning can be a little off and it won’t affect your performance, whereas race gas isn’t as forgiving. I’ve never used any race gas other that MS93, so I don’t have any info on 98 octane fuel.
