How to use 2006 V8 Torque?

I had downloaded 2006 V8 Torque (developer edition) from gp4italia.org . But when i copy and pass new Gp4.exe to GP4 folder, CSM have warning: This is not original GP4.exe file. How to use it?

search this site, there's a file called v8.cap that zaz has come up with, and you simply put it in the patch folder of the mod you want to use it in.

the file is included in ZaZ Utilities Pack

what is this file for .... i think it is decreasing the car power ??? or something lie this ..right ?

It also modifies the torque erogation, to match v8 engines specifics...
