How does APS deal with MAF issues??

Over the past year there have been a few threads on this issue....especially with regard to tuning the Z for boost. With the Greddy TT kit the MAF voltage is clamped under boost to prevent the ecu from freaking out. Because the APS kit uses a piggy back as well does it do the same thing?? I am curious because I know they have some higher boost maps being released soon...just want to ses if they do it any different. Maybe APS can chime in??

I'm pretty sure they clamp it as well, as they include a MAP sensor for their fuel/air maps.

I haven't looked at it carefully, but I would bet money that they clamp the MAF signal with a 4.7 V zener diode somewhere in their cabling or piggyback setup.
