Hi,
I have a question regarding the settings in the esc for modified racing. I saw a setup where the boost end rpm was at 40,000 and the turbo start was at 9000 where it's activated using rpm and not full throttle. I want to understand why would the turbo setting be so low within the boost start and end rpm range. Is it better to have the turbo start rpm closer to the boost end rpm and use full throttle instead of rpm? Any help would be appreciated.
