Just curious but why would you want to?

you need a MAP sensor and an IAT sensor. you can get a factory replacement MAP like the Exo X/JDM MAP or the OMNI Power and get the GM IAT installed in a bung in the UICP. Then, you need someone to tune it.

If you want to completely get rid of the MAF, I think you need an ECU pin or 2 and a diode for the baro sensor. Not certain. I've only actually tuned one of these and have never done the hardware work myself.
