Logged boost vs mechanical boost.

log idle. MAP and BARO should read the same. It's a start.

They read the same.

KOEO THE MAP SHOULD BE CLOSE TO 14.7 but needs to be corrected to altitude above msl, boost should be zero.

Ok. What about location. If you have a boost leak, and the sensors are far apart, could we get this discrepancy under load? Boost leak test next?

Ok, lets start over. Is your CTS reading off across the board, or is it only off at full boost? I can tell you the stock MAP sensor is only 2.5 bar (approx 36 psia). It generally maxes out around 22-23 psig (it will read a little higher at lower barometric pressure). If it is reading off across the board, the sensor isn't scaled correctly in the tune. If it is only off at max boost, your just saturating the sensor.
