25HP lol cant be that much?

Some little things that do make a difference.

1- timing advance (if you run high octane gas) ... good for 3-4hp. If you cant alter your timing by rotating the distributor, you can do the intake temp sensor resistor mod trick.

2- Insulated intake manifold gaskets (you can get these on ebay). Make the car less prone to heat soaking after long traffic stops. Doesn't always ADD hp but sometimes it prevents it from being lost off to heat soak. If they do add power, they do it by making the intake manifold slightly longer which changes it's resonant frequency and usually adds some 2-3hp and some 5ft-lbs of torque.
Sometimes you can find a different model (corolla, camry..etc) with a similar engine with a plastic intake manifold... you can swap this manifold on for the same effect.

3- Throttle body coolant bypass mod (simple to do and dyno proven for a 1-2 hp).

4- 'Voltage Stabilizers'. I know these sound like BS. But I built one on my own and installed it on my benz and it does work. My throttle response is better and my 4000-5000 rpm pickup is better with it.

I talked to a couple of people about this, and our best guess is that it improves your ignition effeciency and response time. So from an ignition event point of view it's the same as having a slight timing advance.

now those are 4 mods that add 3-4 hp. But don't expect a 16hp gain doing all of these together ...

after you do all these mods , reset your ECU.
