4 Questions that are holding me back Before I go any further with my build I have a few questions:
Can I use my MAF in conjunction with a 3bar MAP for now then switch to SD at a later date?
Is it just plain wrong to mount the MAF right before the turbo where it does not see boost vs after the intercooler and right before the throttle body?
Once I switch to an SD tune can I leave the MAF in front of the turbo and still make use of the IAT sensor (truck MAF) vs cutting the wires all together then wiring an IAT sensor into the intake pipe?
Can the MAF be zeroed out/turned off in HPtuners or does it have to be physically removed when running a SD tune?

Surely you can search ?
There are few good reasons to keep the MAF.
Yes you can mount it before the turbo....as long as it's in smooth clean air, but the MAF will run out of headroom far far sooner in suck through configuration.

Not really. In order for HPT to recognize the 3 bar MAP properly, you would have to flash the OS to a 3 Bar tune, which isn't available with a MAF.
Is it just plain wrong to mount the MAF right before the turbo where it does not see boost vs after the intercooler and right before the throttle body?
The IAT is with the MAF. How are you going to get an accurate reading?
Once I switch to an SD tune can I leave the MAF in front of the turbo and still make use of the IAT sensor (truck MAF) vs cutting the wires all together then wiring an IAT sensor into the intake pipe?
So you want to leave a non-working MAF there as a restriction just to use the IAT? The IAT is 2 wires. Cut/strip them, and wire nut them to a $16 sensor/pigtail if you have to. It will take what, 30 seconds?
Can the MAF be zeroed out/turned off in HPtuners or does it have to be physically removed when running a SD tune?
Again, why leave a non-working MAF bolted up as a restriction? If its not being used for anything, take it off and throw it in the garbage. You could also stuff a rag in your intake pipe if you wanted, don't even have to hook wires to it or anything.

So again, don't half *** it. Just get rid of the MAF...

I'll remove the MAF, strip the wires and add the IAT sensor. I have one laying around. Just was not sure if it was the way to go. I see now that it is, no worries.
Is this diagram accurate?

You have a strange infatuation with MAF sensors. Yes, a MAF is more accurate air calculation at low speed airflow values, but speed density cars are more than acceptable in these areas also. You can still run closed loop operation with speed density if you wish. If it makes you feel better, most of the Dodge vehicles (Including the new 707hp Hellcat) do not have MAF sensors. They run on a closed loop Speed density setup, and have been for years. Surely you would agree that a brand new dodge runs smoothly at low speed operation, and also passes even the strictest emissions laws.
