I dont know ifthis belongs here or the nitrous forum. I'm running HSW timing tuner and have the nitrous off at 5900 rpm. I can get the 1-2 shift above this point (about 6000), but the 2-3 shift occurs with the nitrous still on (around 5800) . Is there any way to get the 2-3 shift higher? I have it set at the highest setting right now. The problem is I cant get the timing tuner to set the max rpm any lower. Thanks in advance.
