more boost or spray with kb

[boston03cobra]

it's a 2.4 kb with all the supporting mods with 19psi.the car is pretty much driven daily so what would be the safest(provided the tune is good)upping it to 23psi and running torco all the time or just hitting it with a 40 or 50 dry shot.the car made 587hp/522tq on an 85deg 47% humi 19deg timing on a dyno jet.does that seem a little low.car just doesn't feel as fast as I thought the way everybody talks about twin screws.so basicly I just want to know what's harder on the motor(56k).

Hit it with a 75 dry shot on a Torco tune. Much better than a DD 23lb Torco tune. You won't need the Torco all the time just when you need it. Even with Torco the timing w that 23lbs is only going to be about 17*
