MAF ???'s

[DRASTiK]

you've got a 70mm throttle body. Do you also have the 70mm EGR spacer right behind it? If so, then yes I think a MAF would be worth the purchase for you. And yes, orange injectors are 19lbs.

You don't have to change injector size, however if you planned on doing it any time soon, then now is the time to do it because your MAF must be calibrated to whatever size your injectors are. I use a C&L 73mm MAF. The sample tube inside of it can be changed easily if injectors are changed. Most of the other brands require you to send them off and have them recalibrated if you change injector sizes. With the C&L setup, basically all you're buying is the outer shell. Then you put your stock ford sensor in it and you're done. If you change injector size, then you just spend 20 bucks on a new tube for your C&L. It's a very convenient product.
