Yes, a major backfire (or 2 or 20, in your case) can cause permanent damage to ignition components. Let's take the simplest route to rule some of these things out.
1. Borrow a friend's fuel pressure gauge, and check the line pressure against your gauge.
2. Regardless of your existing problems, you NEED to have a chip that's set up for your exact engine mods, exact turbo, injectors, etc. Given the headaches you're experiencing now, I would HIGHLY recommend that you call Red Armstrong (440-235-3232) and get a new chip. Piece of mind in that department will run you a mere $50, and you'll be dead on for your combination, and be able to rule this out as a potential cause of your problem. A chip that's written for another turbo or injectors simply will not be correct. Period.
3. Do what you have to in order to get your friend's Direct Scan for a day. It is hands-down the best data acquisition tool you can use with a stock ECM. You'll need to do a quick mod to your ECM, as detailed in the DS instructions in order to use it, or borrow your buddy's for a day. Like I said, email me the data file, and I'll be happy to check things out further.
4. If you can find someone who's willing, try your coil pack on THEIR car. See what happens.
5. Again, if you can find a willing partner, borrow a set of 009's from them. Not a big job at all, and one more thing that can be ruled out. See what happens.
6. Triple check the grounding points of the coil pack/module brackets. Using your Ohmmeter, hold one lead on the sheet metal screw on the firewall [with the braided copper ground], and touch the other lead to the bolts that fasten the coil pack and module in place. You should see very little, if any resistance.
7. What fuel pump are you running? How old is it? Again, with all of your current issues, I still recommend that you monitor the fuel pressure under boost, at WOT, in each gear.
