Im new to the whole handheld tuner thing. I noticed that when I take my car to the track, the very first pass is always like 5-7 mph faster than the rest. That leads me to my first question- does the stock tune pull a ton oftiming when you are beating on.the car fairly hard? And 2) Will a handheld tuner fix this? I want my car to be more consistent at the track.

How long are you letting the car cool down between runs? Usually a car slowing down is a sign of heat soak. The computer pulls timing either for a hot engine, hot air charge, or detonation. If a tune is done properly then the timing will still be pulled for any of these conditions.
Get some datalogs of your runs. Watch all the temps. That should tell you what's going on.
