so i have been drag racing for a year now, and my short track has just been horrible. i use boost by vss, and my 2 step is @7100. now on my vss graph you have positive and negative boost so when im stage and in 2 step and wanna come out the hole at 4psi. do i start my line at 4psi at 0 so when i launch im seeing 4psi? im hoping this will increase my 60' times as well as my 1/8th mile

best
60'=1.79
1/8th=7.5
1/4=10.6
mph=141

If you have the error feedback control turned on in the software, and your target boost vs duty cycle mapping is right whatever you set the target at in the VSS vs boost table the ecu will closed loop that value. If you 2 step the car, watch the error feedback values for boost control and your target boost and it should be trimming the duty cycle to latch to the target value if everything is set up correctly.
