If you have done the Sniper EFI conversion, what did you do with the display?

Solution
I removed the ashtray and cut a piece of black acrylic to size and attached it using the existing screws that held the ashtray. I attached the display to the black acrylic with a couple screws.
Have you done the "tape" thing on your sniper? I had to do that. It's been a while, but it worked for me. Read through this if you haven't yet. This may or may not help your issue, but it certainly won't hurt to try.

I made a 3D printed bracket/case to hold it to the lower left of the steering column, using the factory column bolt, no adhesive. It comes up in front of the lower dashpad.
It should be in the 3d print thread if anyone finds it useful.
Sorry I only just saw this… here’s MY story. The IAC% (idle air control) is viewed on the display by selecting “monitors” then the “sensors” icon and the IAC% is in the lower left corner by default. The manual read between 2-10%. And is never adjusted until the engine coolant temp is over 160*F.
Disclaimer: I am no expert but learned all of this the hard way and then, I read the manual and called Holley tech support…3 times!
In my view, the term throttle idle screw takes an old timer to thinking that it is an adjustment screw for the butterfly and while it may be, it just doesn’t work that way. I have my display mounted with a magnetic phone mount and it can be removed and stored easily. Starting? Holy cow…it is a dream. After the 4-5 seconds of fuel pump pressure and reboot…it just starts and runs…once in a blue moon I takes a 2nd start but NOTHING like it is after sitting 2-3 weeks.
I have tried 3-4 different methods to adjust the IAC% and after another call to Holley, the tech told me 14 was absolutely within the target numbers and there is nothing to be concerned about running at 14%.
Can’t say much to the higher elevations… my house is at 167ft above sea level…its all down hill from there
EDIT; I did the tape thing and while it thought it worked, it ultimately returned slowly to 0
