hey i am wanting to get my car remapped for some extra power at the same time i am going to fit a Split-r and a forge TIp and cold side dump valve kit. my question is my friends have CTR'S and Astra VXR's and from this remap i want to be able to really pull away from them but dont know what to go for in a remap as some have high bhp but not as high torque like custom code and others have lower bhp but are different in how the power is delivered any help would be appreciated
