Worried About My MAF/Inj Combo

Im going to be dyno'ing my car next week and after talking with my tuner I'm a little skeptical about my MAF sensor and injector combination. I have a Pro-M MAF set up in Tom's 3" blow-through tube calibrated for my 71 lb injectors. My tuner said it should work but the Pro-M is really touchy when used for that big of injectors. I am wondering if I will be alright with this or if I should change my MAF to something else?

I dont want to run out of room with the MAF either. I have a Precision t3/t4 61mm 56 trim turbo with a built engine set-up to run it to its full potential. Should I be ok with this set-up or is there a better MAF that will work for me? Diablo MAFia???

Also does anyone know where I can get a tuning file for the 71 lb/hr RC injectors that CFM sells?

Are the 71lb injectors you have High Impedance ? Was the Pro-M in my tube when it was calibrated ? The stock Focus electronics in my 3 inch MAF tube with the MAFia works real well also

Pitch Black216 are your injectors high impedance?

yeah mine are the RC high impedence ones that cfm sells. The MAF was calibrated in a pro-M 70mm adapter before I mounted it in your tube. Im strongly thinking about picking up the MAFia before I go to get tuned and bring along my stock zx2 MAF.

Im also worried about maxing my MAF out prematurely. Is there a difference between using the MAFia with my ZX2 Maf and using the MAFia with say, a Lightning MAF both in Tom's 3" tube? Id like to get 400whp on pump gas with it and would hate to peg the MAF early.

If you have the MAFia with my 3 inch tube you have plenty of room to make 400 just watch you MAF voltage and when you start getting close turn the MAFia up more for more room
