2004 GTO LS1 auto
Turbocharged
2 bar factory GM cobalt ss sensor
2 bar custom os
Map sensor linear is set at 210kpa, was as the default 200kpa and same thing. Map sensor offset is default of 10.33kpa
So my map sensor reads off after 110kpa. In my chart, when it starts to wonder off, it reads 110kpa, my afr histogram reads 120kpa. As soon as it hits 115kpa, the histo now says 130kpa. 120.1 it says 140, 125.2 now reads 150.... And so on. The afr kpa is correct because that what my boost controller and boost gauge say. Help me understand what I need to change to make this fall in line, please.
