Could a bad MAF be attributed to excessieve boost?

BTW, the X-chip won't boost past 1.1 bar, and it is usually upwards of 1.5 bar.......
in other words, it is in limp mode. But I am curious as to why the APR chip will just keep giving the car more and more boost.

Yes it could be, although it shouldn't be.. the ECU is normally a torque-based system, in that (m)
it strives to reach a target TQ value under a variety of conditions. The biggest factor from which this TQ calc is derived is the MAF measurement. So in a way, it is striving to reach a desired MAF measurement. This is readily apparent in cold weather when the ECU may cut boost because it can reach the target value without boosting as high.
Howerver there is normally a 'max boost' safeguard that steps in even if we can't hit the target. Honestly, I can't believe APR would remove this so perhaps there is another explanation.
