What is the best way to go with the MAS, I talked with pro-m and was asking on weather or not to send in the factory one to be recalibrated but they suggested the 80mm composite instead. what about the wms advertising up to 17hp increase, I am new to the 4.6 but have seen lots of information for the 89-93 MAS so I dont know if the same applies to the cobra. thanks

I have the C&L MAF. I took it off and put the stock MAF and air box back on to get some warranty work done. After I picked it up today I noticed there as a noticable reduction in top end power with the stock MAF compared to the C&L. I'm on my way out to the garage to put the C&L back on right now!
