GM Maf vs 2G MAS

[Shane@DBPerformance]

The GM MAF should be able to handle more HP before maxing out(most people will never max out a 2G MAS though) and is a little less restrictive. You can also place it after the BOV, which allows you to vent to atmosphere. You can do some AFC style tuning with the MAFT box, but if you have much more than basic setup, then you are usually better setting the MAFT up for stock injectors/zeroed out and then doing all the tuning in DSMLink or an EPROM chip.
