Code 56 means you have a problem with the wiring to or the device itself:
1. Boost control solenoid
2. EGR
3. Transaxle or TCC
Does the SES light stay on at all times, or just when decellerating?

If it only comes on when decellerating, I would say it'* your boost control solenoid. You need to replace it.
The diagnostic is from the GM service manual.
We have seen your problem numerous times before.
