Newbie with vacuum lines ????

A manual actuator can get you more boost for better power on the stock PCM, mainly because the PCM allows 10 seconds of higher than expected boost before it throws a code. Adding a boost fooler (just a potentiometer on the boost sensor) you can run a little more boost.

You can always run a 3 bar MAP on a stock ECM and get by without a code so long as you keep the boost under about 12-13.
