What exactly do you mean, not working out correctly? If you bought it used, you need to get it reprogrammed to your exact computer code, so unless the person you bought it from has the same computer code, you just need to get that reburnt to your code. With the mods you have listed in your signature, there is no need for a complete custom burn, unless if your running on the funny juice, or turbo/supercharged. You just need to find somewhere to burn it to your computer code. try
