the best you'll do is 14.8 or so; that's the absolute best i've heard of / acheived on a stock 5th gen, base or sh. low 15s are more common.
i've run mine with a gtech dozens of times, and gotten results from 14.8 to 15.3 depending on the temperature, amount of gas, time from last oil change, wind, traction, etc etc etc etc. of course, the gtech may be off by a bit; i trust it though. i have a 2000 sh.
