You are going to attempt to fool the TB model into thinking MAP is a few PSI less than baro+your delta baro table. I don't see you having much luck doing that, and if you succeed not causing some other unwanted behavior. There are maximum and minimum learned baro tables, you would want to start there making the maximum 36inHg or something higher than actual baro. Make the minimum the same. You want it to think baro is higher not lower.
