I was looking over a 2007 Cobalt SS tune file and i found this
Operating system patch
This patch will extend the VE table range up to 255kPa (21PSI).
ok well 255kPa = 36.9psi
so i just thought the conversion was wrong but then i remembered something from my EVO tuning software. it's tuned using engine load, and boost cut just so happens to kick in at 255 which is 21-22PSI.
my question is what is correct and if the 255 refers to engine load is that what we should be using in our MAPs instead of kPa.
or is there a table missing or am i just crazy
