Blackwing or Vararam???
You aren't going to see the performance gains that the VaraRam gives by looking at a dyno chart. When a car is dynoed, it is SITTING STILL!


Loosen the very bottom clamp on the MAF sensor that connects to the lower filter housing and then snug down the upper right corner of the upper housing.
You have to push in the fan shroud to get it to fit snug.
Then tighten the lower clamp on the MAF and you'll see it fits fine.
This is what I discovered on mine. Same problem as yours.
I also discovered that the air bridge does not align up straight to the throttle body and that is where the problem is.
When you align it and connect it, it kinks the upper air box and hence the gap in the upper right corner.
I had an aftermarket air bridge and it will work, you have to do the same thing as above for it and the stock air bridge.
After a lengthy conversation with LFPE on air bridges, I put the stock one back on and it actually helped smooth down my idle.
The VaraRam is overall real nice; Kinda a hassle to install at first, but it's easy to change the filters; Run the flimsy filter on track days and dyno days, run a more robust filter for cruisin'.
