I have been doing quite a bit of digging online and I cant find in the Trans or the ECU tune ware to allow the trans to shift 6th at wot. I know other tuners have made it happen. Not sure if maybe its a HP tuners feature?.
I just spent hr or so on the dyno playing with the 5-6 6-5 shift stuff since it looked waked compared to the other gears but no luck on getting it to shift.
I am planing on doing a rolling 1/2mi race and I am pretty sure I will need 6th gear for that.
