I think those times all sound about right for a stock SH. Trap speed is right on, but I'm sure your tires were under inflated so you could make a few tenths there. I never raced stock, but with I/E/P I ran consistent 15.0's @ 92mph in my SH. 2.2xx 60 foots too.
Keep up the racing, and start modding!
And remember guys! The SH is heavier!
