There was a topic retrac and I were pondering a while back and I want to ask.

On a target boost chart, if it is set up so that it's targets are linear throughout a throttle position and you use the boost controller to then vary the boost, is there a benefit to this?

basically 50%+ throttle was set at 19.81 for all rpm ranges and under 50% was set to a different number, the adjustment was then done by the boost controller. I tried this tune, it boosted like a raped ape and seemed to bring lag way down, however we didn't play with it long because for some reason the tune we jacked had some idle issues cause 10:1 afrs at idle and IAM's of 1 or 0 at times (16 bit). So have you ever set a boost chart up like this, and could you make it work like that at all?
