i would say the rough guideline would be like 210-250 , some people on here with standard engines have made 240+ bhp it all depends on the condition of the engine the turbo and the map ya get etc , ive been td04 for 2 days no im on a stndard engine and its done over 200K+ and i havent had any problems .... yet lol im going to get mine mapped to 1.2 bar and im aiming for 230bhp i havent changed my headgasket and i doubt theres a need too if i was you personally id ditch the rrfpr and fcd and get a proper management , im going to go emanage blue and help on the first time install , keep some money back and expect some modding or something to go wrong lol
