26" or 28" slick?

I ran a 26x10x15 MT ET Street last time at the track. Car ran really good and I ran a personal best. Only problem I noticed was that I was very close to shifting into overdrive as I crossed through the 1/4 mile traps. Should I keep the 26" tires or move up to a 28" tire? My car should be a high 11 second car, see sig.
thanks,
Patrick

115 mph is where some make the switch... Do you plan to turn the wick up and use them?

Yes I plan on turning the boost up. Last time at the track I ran 21lbs of boost and I plan on eventually running around 22-23.
