The downside, of course, is that if you disable the air temp sensor for speed density operation inside the ECU, then you need to make sure your air temperature reading while doing your calibration drive is fairly reasonable (say between 50-90F). A good working intercooler and some careful attention to your right foot will help immensely with this too. | The downside, of course, is that if you disable the air temp sensor for speed density operation inside the ECU, then you need to make sure your air temperature reading while doing your calibration drive is fairly reasonable (say between 50-90F).

To ensure that this isn't a problem, you have to use one of our newer GM MAF cables that provide a separate power wire for the GM MAF's grounding point or you need to [[gmmafcablemod|modify our older GM MAF cable]] (if that's what you have) to add this wire. | To ensure that this isn't a problem, you have to use one of our newer GM MAF cables that provide a separate power wire for the GM MAF's grounding point or you need to [[gmmafcablemod|modify our older GM MAF cable]] (if that's what you have) to add this wire. | ||

This modification involves simply cutting the ground wire on the GM MAF connector and running it to chassis ground instead. |
