Hey guys. Just recently picked up a '08 LNF Cobalt and have been learning a bunch. Have a turbo '01 LS1 SS so I'm not new to tuning but as everyone says this ECM has some tricks.
Followed most of the guides here and its running well but I am commanding 95% WG DC and only seeing 75% DC for most of the run. (long log file but its towards the end). Boost goes to about 22 psi and holds okay but then tapers off after 5500. Boost holding seems decent and inline with what others have on the same stock turbo, just wondering why the commanded doesn't match the actual for the WG DC?
