why is my car so slow...

[mustangman7777]

my k&n is a bit dirty, the weather was like 60 degrees a bit cloudy no rain or anything, the track is not that high, no more than like 2000, i could use a good tune up i am thinking about getting it dyno'd to see if that reveals anything. i was not hooking up good and my shifting could have been a bit better, it was ok, but not great. i tried shifting at like 57-5800, and 5300 or so both times were 14.5 and 14.4. but as far as i understand it most of the launch stuff will not greatly effect the mph, i know that even when i first went to the track and couldnt drive a stick well at all i was running 15.6 at 95 still.
