I changed my TD continuous yesterday to match a 03 JDM MAP so, the table is symetric around the 0 boost error point. In my runs yesterday, I notice it gets to boost and stablizes around target boost much quicker now. With the USDM map. there were large negative corrections if you overshot target boost. This causes you to undershoot target boost when you have even a small boost spike. With the change, you may still undershoot some but, usually it's under 1/2 PSI where before it might be 3 PSI. I do seem to have some tip-in knock but, that's unrelated.
