Now I have a totally different setup as far as a blower goes (ECS / Vortech) but I can guide you on what we had to do with my car to get things smoothed out.

First - my MAF was relocated also - and on the ECS kit, it actually gets moved to the output side of the intercooler. The problem is that it is like 36" down the tubing from the intake, and my tuner thinks that (1) the sensitivity of the air speed may be a little sluggish due to how far away it is, and (2) there could be some kind of harmonic / reverberation issues. Needless to say, I would have weird MAF readings (the MAF output would fluctuate even though it would be under a steady load / rpm - like +/- 10%).

In my tune - as he has some kind of master HP Tuners license - he was able to build a custom table that basically cheats the MAF sensor by converting the sensor data to fake MAF data that the ECU reads. I can see it in my tune, but cannot modify it because I do not have the high level license that he has. *no idea how to get one either*

Secondly - since the MAF is so far away - it came with a extension harness (similar to that of the ProCharger one). The connector they supplied was not real good quality where it met the factory ECU plug, so I myself ended up using their wire to extend the factory plug. Since doing both of these, I have not had any more weird MAF problems

The reason to run a separate IAT sensor is the fact that prior to putting one in, the ECU is reading air temp at the MAF. If you move it more than about 12" or so from the throttle body, it is really no longer relevant. And something else to consider is that the temp sensor you put into the intake is a much better, much more robust sensor also. The ones in the MAF are really setup just for stock-ish type work.

If you are running anything like Meth Inj / Water Inj, you pretty much need the IAT breakout as you are injecting behind the MAF

This might be to much to ask but can you send me pics (PM) on where everything is relocated on yours, I know it is a different setup but helps me have a few options on the table. As far as your tune i'll mention the type of procedure to my guy and see what he thinks, I am running the RPM custom meth kit and have purchased the breakout harness. so did you have to drill into your intake manifold after the throttle body to get that reading now?
