Sounds like you bought yourself some drama! That kinda sucks....
I'm not the authority on these types of things, but if I had to guess, you'll probably have to pay if you want to have it tuned either by the previous shop or another of your choice.

Curious if I could buy new ECM with paired keys and start over from stockWelcome to

I don't think you're going to be able to run that stoker on the stock PCM/tune.
I think you're going to have to find another performance shop and get a tune done.

Not sure if the paired keys part applies cuz I've been told that the 07 security system and ignition system were 2 separate things
I know some tunes won't install unless there is one in it to pull out,I thought I could maybe install custom tune myself if I had made online if I have stock tune to pull out

If they returned it to stock - wouldn't it be the stock tune that runs it now. If so, another tuner may be able to write you a new tune for all your modifications. If you get a hold of Brent at Brenspeed he would be able to advise you if they can or not. He worked with me with tunes from 2006 through delete plates, underdrive pulleys then Comp Cams VSR and finally the Saleen S/C 530 hp and was always very informative and helpful. There are others that use Lito for theirs. There should be a solution for your dilemma.

When I tried an off the shelf tuner it couldn't put anything in because there was nothing to pull out,is how it was explained to me, I'm new to the whole tune thing,an older SCT tuner came with the car,tried to update it but too old,it does get into where I can set perimeters but I have any idea what they should be so haven't messed with it
It sounds to me like you need to get it in someplace and get it tuned before the whole damned thing goes:
A boosted application is not the place to be experimenting. You are one lean pop away from total destruction.

Don't know if an off the shelf tuner will work. When I got my XCal 2 (Old as the hills) I had to supply my ECM Strategy to Brenspeed before they could write the tunes and it's married to the ecm and won't work to program other vehicles. The Sct tuner downloads the stock tune and retains it if it's ever needed to return to stock and it has to be returned to stock before it can be reprogrammed for a different vehicle. I still use that Xcal 2 to this day and it worked for all the subsequent tunes I got. It has a few parameters I have experimented with timing and others without hurting anything. Generally canned tunes are written pretty safe so you can't screw them up - Dyno tunes - I'm not sure. You can always download your vehicles strategy from https://www.motorcraftservice.com/AsBuilt, but you would need a method to program it and then retune car with all the mods. Forscan is one program that some use to program the original As-built, but in your case that would have to be carefully researched before.
