I did almost the same setting except the pinion gear is 21T in JV....corner handling is good but lost a lot in straight road ( increase boost can have more speed in straight road but lost handling in corning)...beside the energy distribution is bad that the speed trigger is pull 90% in the corner exit and lost more in straight road after 3~4 mins run... replaced the HW 1S, off the boost/punch for better corner handling and make over 80% turbo will bring u crazy speed in straight road thru out 8 mins!! I am quite sure HW ESC is the only way to beat down the 4WD touring!!
