I never said they were a good idea. They are a fix (work well for it, too) for overboost codes and defueling. That's it. People have been sending 40+ PSI of boost to the MAP sensors for years without problems.
If you think about the terminology.....
MAP Manifold ABSOLUTE Pressure will be way different than Turbo Boost GAUGE pressure......by about 14.5 PSI (or whatever the barometric correction is).
