Stock or Aftermarket MAF Sensor

First off I hope this is the right place to post this. I've built a 1999 Explorer engine for my Ranger. I decided to use the Ford Racing 30 Lb. injectors because I thought more fuel, more power and because they are red and match my color scheme. I now understand that's not always true but what's done is done. We have the engine up and running but it runs much better when the MAF sensor is unplugged. It's stock so it's calibrated for 24 Lb. injectors. My question is, should I stick with the stock one and let the tuner set it up that way or would it be better to get an aftermarket MAF sensor calibrated for 30 Lb. injectors? The engine's bottom end is relatively stock other than hypereutectic flat top pistons but the top end consists of custom aluminum GT40 heads, a 270 roller cam, Trick Flow upper and lower intake and an 80mm Trick Flow throttle body. I don't want to spend a few hundred bucks on a new sensor if the stock one will work just fine!

Calibrated MAFs are for people that can't tune... For example, I run 31lb Volvo injectors on a 4.0 Ranger MAF.

Stock for a 4.6/5.0 should be a 19lb injector, and I believe the 5.4 and 5.8 got the 24s.
