How to replace a config.cpp

I've been seaching for a tutorial on "HOW TO REPLACE A CONFIG.CPP" but didn't find any one.

What I'm trying to do is very simple: to change speed and acceleration of TT650 motorcycle.

I unpacked wheeled3.pbo with extractpbo, changed maxspeed to 1000 and packed wheeled3.pbo again, made a mod folder as "@tt650\addons\wheeled3.pbo" and nothing happened.

I know I could have deleted some files like p3d and textures but I don't know exactly which one of them.

Can anyone help me.

Did you remember to add the name of your mod to the target line parameter in your shortcut ?

Yes. I did.

Simple example of a replacement config:

class CfgPatches {
class AnyClassNameThatDescribesYourAddonComesHere {
	units[] = {"Su39"};
	weapons[] = {};
	requiredVersion = 1.51;
	requiredAddons[] = {"CAData", "CAWeapons", "CAAir2", "CAAir3", "CAWeapons_E"};
};
};
class CfgVehicles {
class Su25_base;	
class Su39 : Su25_base {
	weapons[] = {"GSh301", "GLT_Ch29Launcher_IR", "R73Launcher_2", "S8Launcher"};
	magazines[] = {"180Rnd_30mm_GSh301", "GLT_4Rnd_Ch29T", "2Rnd_R73", "80Rnd_S8T"};
};

};

This config would replace the armament of the default Su-39.

- Load the class your objects inherits from:

class Su25_base;	

- Load the class you like to alter:

class Su39 : Su25_base {

- Change what you want to change (no need to copy/paste the whole config here):

	weapons[] = {"GSh301", "GLT_Ch29Launcher_IR", "R73Launcher_2", "S8Launcher"};
	magazines[] = {"180Rnd_30mm_GSh301", "GLT_4Rnd_Ch29T", "2Rnd_R73", "80Rnd_S8T"};

Hope this helps. This method works for everything that is defined in a config.
