Boost question.
May be a weird question, but is there a way to slow down how fast boost builds? Thinking if max boost could come in a little slower driving on road courses may improve. Not looking to limit max boost.

NLR, Next Level Racing makes a boost controller that is well respected in the motorcycle world...If I'm not mistaken it can be used on cars as well...The device has setting to bring on boost by time, gear position, etc...Check them out they may be able to assist you in this area...The device is called the AMS 2000...

Thanks for all the info guys. Still working on that right foot :-)

Can a controller be sourced to activate based off the manifold pressure???Just asking as there appears to be several boost controllers available for superchargers that are not related to any function of a wastegate...

No. If you want boost to come on a little slower and linear, ditch the pds and go centri

I believe this is what you are looking for.

I forgot about that table. I guess you can lower the duty cycle and slow boost that way. Here's a description from GM on how it works.
The ECM controls boost pressure by using the boost control solenoid. The boost control solenoid is normally an open valve. Under most conditions, the ECM commands the boost control solenoid to operate at a 99–100 % duty cycle. This keeps the solenoid valve closed and allows only inlet vacuum to control the position of the bypass valve. At idle, engine vacuum is applied to the upper side of the bypass valve actuator, counteracting spring tension to hold the bypass valve open. As engine load is increased, engine vacuum is decreased, causing the spring in the bypass valve actuator to overcome the applied vacuum, closing the bypass valve and allowing the boost pressure to increase. The bypass valve starts to close when the vacuum measures 10 in Hg and is fully closed at 3.5 in Hg. When reduced boost pressure is desired, the ECM commands the boost control solenoid to operate at a 0 % duty cycle, but may command a partial duty cycle, approximately 62 %, depending on the operating condition. This opens the solenoid valve and allows boost pressure to enter the bypass valve actuator at the lower side to counteract the spring tension, opening the bypass valve and re-circulating excess boost pressure back into the supercharger inlet.

You can also control the boost ramp in rate (to a degree at least) by adjusting the Boost Solenoid Duty Ramp Rate and Boost Solenoid Integral Adjustment.

Great info. Thanks for the boost control info ABADZL1 and DrkPhx.

And of course thanks to Z06 Bryan and STUNNAH. I feel properly and politely reprimanded:-) Was that to touchy fee-lie?
