i tried using the transbrake after doing suspension mods on first pass of the day. It went how you would expect. i don't think ive seen any ecoboost 10r80 transbrake 1/4 mile runs. I definitely wasn't paying enough attention to boost and datalog shows i tried to leave on 9psi with rpm limit set to 2200. Is the transbrake useable at all on street tires or is 3.55 and 1st gear too much torque? Or is there a way to change boost level via load setting on the accessport?
