I imagine if the map sensor isn't getting information you're probably going to run stupid rich.
best thing for improved exhaust is upgrading your fuel delivery (ie injectors, fuel pump) and fuel management (anywhere from SAFC stuff to standalone). also, if your car is turbocharged, port your wastegate so you don't overboost.

Mazda realized that loss of the MAP signal would be catastrophic, so the ECU goes to default mode if the MAP signal is bad.
However, pulling off the hose may not be detected - & BOOM!
Same thing if the FPR hose fails, only the ECU has no check circuit for it.
The fuel cut is a safety to keep you exceeding the limits of the stock fuel system & ECU maps.

Thanks, just curious, cause my friend is swapping a TII engine into something, and is fabbing a straight through 3 inch exhaust, and is using the stock ECU, better feed him this info.

The cheepest way to make more power:
a mechanical boost gauge to verify actual boost levels
a wideband AFR gauge for tuning
720 secondary injectors
A fresh rewired 255LPH fuel pump
A rising rate FPR or an S-AFC
port the waste gate to prevent out of control boost
FCD
a header dump or a big exhaust
a high flow intake- smooth TID behind a CAI
a boost controller to push up boost- a manual BC with a bypass circuit works well, electronic is better
at rebuild time- port the engine
To go any higher you're looking at a FMIC, Stand alone ECU, and a bigger turbo.
