   * Can provide some restriction to airflow to the turbo. ​ This can be a hot topic for debate, though. ​ We generally feel this restriction is minimal at best and for most people should not be a major consideration. ​ Just make sure you replace the stock snorkel between the MAS outlet and turbo inlet with a larger pipe and you shouldn'​t have anything to be concerned with on this topic.   * Can provide some restriction to airflow to the turbo. ​ This can be a hot topic for debate, though. ​ We generally feel this restriction is minimal at best and for most people should not be a major consideration. ​ Just make sure you replace the stock snorkel between the MAS outlet and turbo inlet with a larger pipe and you shouldn'​t have anything to be concerned with on this topic.
   * Have some very real limitations on airflow metering capacity. ​ This is particularly problematic for the 1G DSM sensor. ​ The 2G DSM is better and the EVO8 is really very nice.  Some details on the limits can be found on our [[maffrequencylimits|MAF Data page]]. ​  ​Generally speaking, a 2G DSM MAS with ECMLink'​s MAFClamp function can work well to 30psi on a 2 liter engine. ​ An EVO8 MAS works well beyond that, particularly when combined with ECMLink'​s MAFClamp function.   * Have some very real limitations on airflow metering capacity. ​ This is particularly problematic for the 1G DSM sensor. ​ The 2G DSM is better and the EVO8 is really very nice.  Some details on the limits can be found on our [[maffrequencylimits|MAF Data page]]. ​  ​Generally speaking, a 2G DSM MAS with ECMLink'​s MAFClamp function can work well to 30psi on a 2 liter engine. ​ An EVO8 MAS works well beyond that, particularly when combined with ECMLink'​s MAFClamp function.

 Honestly, given the typical installation of these sensors on the typical DSM, I'm surprised they work at all.  But they do work and they can be made to meter pretty well even though we're pretty much breaking every rule in the book about their installation and operation constraints. ​ I guess that says something positive about the sensor design after all. Honestly, given the typical installation of these sensors on the typical DSM, I'm surprised they work at all.  But they do work and they can be made to meter pretty well even though we're pretty much breaking every rule in the book about their installation and operation constraints. ​ I guess that says something positive about the sensor design after all.
  
-We do provide a [[v3mafadjcombft|dial-in procedure]] that helps get airflow working right and, as I mentioned, they do seem to work pretty darn well once dialed in properly. ​ When I run my car on the GM MAS, I can't tell any real difference between it and a Mitsubishi mass airflow sensor or speed density. ​ It works fine for me and countless others. ​ Some people, however, do have problems. ​ Particularly with moisture issues.+We do provide a [[v3mafadjcombft|dial-in procedure]] that helps get airflow working right and, as I mentioned, they do seem to work pretty darn well once dialed in properly. ​ When I run my car on the GM MAS, I can't tell any real difference between it and a Mitsubishi mass airflow sensor or speed density. ​ It works fine for me and countless others. ​ Some people, however, do have problems. ​ Particularly with moisture issues.  Even on my own setup, when my turbo started to develop a problem that allowed some oil to get into the intake side of things, the GM MAF got very upset and I knew pretty quickly something was wrong.
