Octane and Timing

today we logged a couple of pulls on my stock tune car. I am doing Ted jannetty flex fuel conversion next week. Right now I blend gt260 Sunoco with 93 to get around 96 octane. Todays log we saw up to 24.5 degrees of timing. I was surprised as I hear stock is usually around 20deg ? Also I have done LT's with cats and full exhaust, rotofab , and today I put the LT5 tb from jannetty. Other then turning off the rear cats, no tuning, no codes, and it runs like a scalded dog. I know Ted's tuning will help immensely though. So is that much timing unusual with stock tune ? The car seems to have learned to use the extra octane.
