I guess it depends on your car. Different cars require different pressures. Higher boost launches you would want more in the bags. On my car I run 7psi in the drivers side bag and 17psi in the pass. side. The car leaves straight and my best 60' time with a stock suspension has been 1.60. Running 28x9 M/T E.T. slicks.
I would probably start there and then adjust to see what your car likes the best.
HTH.
