from my experience the chargers gonna have you by maybe no more than 2 cars.
you can go to any autozone,orielys etc and they have a 10 minutes tune up wich will only cost like 20 bucks and it will add a bit of hp to you i think olny like 5 but hey its worth it.
another mod that wont cost you a peny just a little of your time, take out yor passenger and rear seats you loose wait that way, and you can always put them back in.
bolt on dont give you much push for hp and yes you do have to get inside the engine for more power, thats what alot of v6 driver (not just mustans) dont do, like the smack talking kid at school or something.
iin mm&ff they did a tech story on the top 10 best priced mods all of which are under 500 and a few you can do yourself.
1.rear gears

6.10-minute tune up (what i was talking about earlier)
7.exhaust upgrade
8.cold-air intake
9.intake manifold upgrade
10.brake upgrades
all of those cost you under 500$, note i said Under, i didnt say all together they would cost 500$
