If something seems cheap, easy, and reliable... chances are it's a scam. If you think it sounds like a good idea, and it seems too good to be true, it probably is. If you notice yourself considering the "too good to be true" stuff, take it as a sign that you need to learn more about your car!
Learn about your engine and how it works. Then you'll know what's crap and what isn't.
Just remember, the engine is a giant air pump. Oxygen makes power. The denser the air, the more oxygen is in it. Colder air is denser. Compressed air is denser. Air mixed with a chemical oxidizer (nitrous oxide) is denser. Fuel is needed to control the explosion. Ideally, you need just enough fuel to do the job, and no more.
These programs usually dump fuel into the engine. They like to say "more fuel = more power!"... Quite the opposite. You DO need more fuel when the mods call for it (like a turbo system), but doing it to a near-stock engine will only hurt performance and gum up the works. If they "lean out" the mixture (less fuel) you might make more power... but you also are likely to damage your engine.
Chips, resistors, or anything that "tricks" your engine is a scam. Once you have enough done to your engine, you CAN reprogram an ECU (Civic ECUs are commonly used in our cars) to adjust the fueling. In that case, it's a viable option... but it's not a $15 option, unless you really luck out!
