Will 28" tires to 26" hurt my ET ?

I ran my car last weekend for the first time at the track. Currently running a 28x12.5 drag radial, car was spinning but ran 11.40's.
My buddy gave me a set of 26x10 slicks with lots of life left in them. If I drop 2" shorter tire, will this improve my ET or hurt it ?

Some info on the car....
peek TQ is 4250rpm
peek HP is 5800rpm
gear is 3.55
was crossing finish line at about 6200rpm with 28" tire

The results.......
Put on the 26x10 slicks and the car hooks hard now.
The results where no surprise other than the trap rpm
Car ran 11.50's and trapped at 6000RPM
So the slicks helped me get off the line quick but the 2" shorter tire ate up the difference over the rest of the track.

Next year I will be running a 28x10 slick and a 3.91 gear:burnout:
