In theory, you want to burp as close to the resonant frequency of the car as possible, i´m saying in theory because this isn´t a constant, for example, my explorer´s resonant frequency is 51 hz but i´m using big ass and efficient boxes now and they peak lower than 51 hz but i still get louder on the meter
Anyway, yes you want higher frequencies for comps, you just need to get a shorter port with a higher frequency and leave your current port with a 35 hz tuning for daily. Said that, easiest wat for you would be to find a meter for an hour or something like that, get a 40 hz tuning port and start cutting the lenght of that port until the score starts dropping on the sensor, that would be your comps port, if you don´t have acces to a meter, then i would say something like 45 hz tuning port for comps?? i dunno really, i´m just throwing ideas...
