From reading the guide's hardware requirements I have 2 questions:

A typical car that would necessitate an SD tune
would likely max out the factory MAP sensor and require an aftermarket MAP sensor to be installed
It basically says you need an aftermarket MAP Sensor. Can you all give a recommendation on a MAP sensor?

The MAF sensor assembly must be installed and properly calibrated if the MAF mode, hybrid
mode, or estimated VE monitor is to be used. It must also be installed if the factory IAT sensor (which is part of
the MAF sensor assembly) is to be used for SD (rather than an aftermarket IAT sensor).
From reading that it sounds like the maf can be removed and an IAT sensor be used instead if going the pure SD route, can you all give a recommendation on an IAT sensor?
