lol @ your fuel table. Ask your tuner why you're squirting more fuel at 5200rpm than 6500rpm, then tell him to **** off, pull the head, inspect the pistons, call your attorney, then drive the car to one of the MiataTurbo trusted member/tuners and pay them. There is absolutely, positively no excuse for a fuel table that looks like that from anyone...from a "professional tuner" it's criminal. Again, no excuse for tuning that looks this bad.

The attorney is not gonna help due to that piece of paper I signed releasing all liability. Hustler I kinda don't want to **** with tuners anymore. I am bound and determined to figure it out on my own at this point. I mean what's the worst that can happen? I blow my **** up? Oh well, it's gonna happen sometime. So now then what do you suggest? Any pointers for a dumb *** like me to start with? Other than trimming some at 5300k or so.

No, you won't ever blow it up if you tune it right.
Read this.
I'm by no means a pro, nor do I have a respectable understanding of how these small computers work, but this is the way it's done by those in the know.

Use arithmetic to reach the required AFR target.
For instance
If you are at 10.7 AFR and your target AFR is 11.7 AFR then you're 8% too rich for your target AFR.
Use the hydra math operators on the appropriate fuel cells to multiply by the appropriate integer. Then interpolate. Then log, then look at log, then repeat process.
If you have difficulty doing this, then I will tune your **** for nudes.

Nudes? Elaborate please. So about the stutter on top. See anything that looks obvious? As far as target afr's go I think 11.7 is about what everyone shoots for right? Also when it comes to the timing, should I put some more in, or just leave it and tune the fuel map for now? Also in the target afr table what happens when i start messing with that? Does that actually change the timing and fuel tables if i mess with that? Oh and one more thing. What exactly is bad when it comes to the knock. I guess I mean what numbers do I start to worry my ***** gonna blow up?

Hydra does have autotune but it may be to slow to respond properly under WOT. Only one way to find out though. Also, from "the factory", meaning the FM base map, autotune is disabled if TPS is over 70% or whatever.

AFR target table is only used for closed loop. And autotune.
Don't tune timing until you understand what timing does, how to look for knock, where MBT is, blah blah.
BTW your **** is not fucked up as it is. Not the best at all, but not horrible. As I said, your power takes a **** because your boost takes a ****.

The hydra manual sucks ***. I read a lot of it, but I wouldnt exactly call it user friendly at least not for a moron like me just starting out. Guess I missed the spot about afr's and auto tuning. I get the gist of timing, but looking for knock is something I still would like to educate myself on. So the knock ramp table tells me I'm doing it wrong?

Yes, it is not user friendly.

Man, I hate reading. It makes me feel stupid. Especially the hydra manual. Oh well. I'm gonna start messing with my fuel table and turn my dwell up a smudge as per Jeremy's recommendation. He did give me another really good piece of advice. He said that in general with that much boost if I were having a spark issue that it would show up at a much lower rpm. Really wish I knew what the problem was.

Don't turn up dwell everywhere. Only turn it up for the RPM range that you're having your stutter.
Remember to make change, log, look at log, adjust, repeat. Also use the math functions like I said.

Ok Faeflora pleas elaborate for me on the dwell for me. I see a dwell setting, and excuse me as I'm not at home and dont have the program in front of me. But i know there is a dwell rpm setting that I'm pretty sure is blank on my map as I think you can see, and the other dwell that just has voltage not associated with rpms just volts. I take it I dont turn those up? Do I add dwell in the rpm map?

Curious, did the same guy do your baller initial tune and the FUBAR tune?
When you do get around to messing with timing, you'll need det cans to listen for det.
Cupping is good. Make sure we can see your face so we can use the pictures against you in your upcoming political career. Based upon your demonstrated competence with tuning, I would say a run for Congress can't be too far off.
