Didn't you find an SVT MAF??  After we put are SVT MAF on, the car runs better.  He still has the stock MAF but isn't willing to part with it yet.

I'm running the SVT maf right now... and here's what I noticed (at least with the vortech kit).

Anything below boost is about 20% less airflow than what the stock MAF Transfer functions would lead you to believe. Once you're into boost, it levels out and the MAF gives numbers the stock transfer function indicate.

When my car was at the shop, they were able to drive the car with the SVT Maf, running the stock MAF transfer function... with 0-2% correction below 4,000 RPM partial throttle... but the graph appears to catch back up at about the 3.5 volt level with the SVT stock values.

I need some WOT runs to say for sure..

I'm not quite willing to part with my stock MAF either.. it's my trusted backup plan.
