@ traxxas-modifier - thanks for the reply bro
i've already changed my rear sprocket from 39T to 42T, and im pretty pleased with the result,
smoother acceleration ang gear shift, maybe it matched my driving style.
re: mainjet #105, can i order it as a single item or does it come with something else?
and by the way, i think adjusting the TPS position do raise the rpm limit a little. here's my observation:
i use an 18 LED tachometer, and in my settings, i never get the 18th LED to lit up, since i reach the rpm limit with the 17th LED blinking
after adjusting the TPS position, i can lit up the 18th LED without hitting the rpm limit
i think it added 500 rpm to the limit or a bit more.
can't give a more solid proof though, at least until i make myself a digital display tachometer
