Need more bottom end from my 3 port R.
I have good mileage but need more power.
It's great at the top end...managed to pass an OS speed in the straight at the last race and he went into it sooner than me!!!!!!!
I'm using 2047 and jp-1 wxhaust.
Mugen carbon shoes with 1 or 1.1mm springs

With the 1.1 is better but you have to wait for the midrange to pick up in order to get going fast.
