yeh. the hi throttle and lo-throttle percentages are what i have set to 70 and 69. and that is semi correct, once you set your base fuel pressure to what is needed by your ecu/engine then the TCCS should take care of all the "normal" driving situations. what base fp is necessary for your car could be entirely different than mine as i have different injectors and a different car. my base is set to about 32-35psi. you find what your particular car "needs" by checking your Vf voltage. are you familiar with this? if not, feel free to pm me and ill try to explain it more. i will also say that i am not a professional and i am just telling you what has worked for me and what i have read and learned from other users. hope that was helpful, like i said, pm me for more clarification/help.
