100 Octane will always give you a boost. I personally like the 110 leaded fuel but can't afford $6.00/gallon. So I use 91 pump gas and accept the lowered performance. I'm running about 10.3:1 compression. So, if you are bothered by the hesitation, there are a few things you can try. Do you know where the timing is set at idle? Try advancing the timing a couple of degrees at a time, up to about 16 max at idle. Performance should max out about 14. At least that's been my experience.
