It looks crazy but I wanted to ask experts as it might hurt the engine. I want my Euro 560SEL 1989 (full options) to be a bullet. People here in Kuwait advised me to replace the catalytic converter with regular pipes and get rid of the O2 sensor but I won't do that. I'm just thinking what will it be a bullet if I manually activated the 9th injector (the cold start valve) while accelerating on 560SEL 1989?

I feel its performance is less that my old 560SEC 1989. I've done almost everything except changing the two fuel pumps.
