I decided to get into tuning my car myself and I have a 123mm MAF housing with a 05+ Ford slot sensor (Whipple crusher setup). How do I get an accurate transfer function that I can plug into my tune? If someone has this, obviously that would be sweet. But just having the factory MAF function from a GT500 or something and doing the math for my setup should work. These guys PMAS have awesome transfer worksheets right on there website, and they look like Ford sensors. Can I use that info, or is it way different than the OEM Ford? I guess I could ask them directly. Also, could I send my meter somewhere to get it flowed with a transfer sheet?
