Are there any Hyundai enthusiasts in the Chicago area or a shop that might be able to help you with doing some data logging?
When I've followed people in the past who've started chasing issues like this, being able to pull data logs from the sensors in the engine and then put those logs where the the "nerds" with the really deep knowledge of engine management could see them helped nail down the real problem(s).
Don't know if you have the patience to go that deep.

Your right, I don't have the patience but more importantly the intellect for it either
The data logging has been suggested to me but I guess you gotta buy some program for the laptop and start driving, get the data and send it to the tuner for "fine tuning", this is, as I'm sure you know, is an "off the shelf" tune
He said previously it's "high timing, low boost and I have no idea what degree timing I have my boost is 20-22 psi depending upon the weather
Over the weekend I'm going to my buddy Hectours and bringing my stock ECU, 13K original plugs and just incase, the infamous MSD coils. He wants to start with swapping the ECU and taking it out right away and see what happens, if it doesn't do it we know it's the tuned ECU, we'll also swap the stock plugs back in as well...then call it day, back to 295 hp and 269 lbs ft, what a step down

From the logs I've seen it's certainly not for the faint of heart. Total gibberish to me, but I've seen conversations on forums where a couple really smart people pick out bad values in minutes and talk about what might be causing what they see. Pretty interesting to follow.

That's why I wondered if there was someone in your area who might already have the equipment and software and would do it as a favor or for a small fee. I know for other cars with a history or tuning (JDM or German) it isn't hard to find someone on a forum able to decrypt the logs. Not sure if the Hyundai modding community has been around long enough to have developed that level of depth yet.
I do full appreciate not having the patience to go through all of that, and honestly I wouldn't either. In the same position, I'd take the car back to a "known good" state of hardware/software and leave it.

That's still not too shabby for a car that size, but I do get what you're saying.

Re: From "stay tuned" to T U N E D !!
What does he mean by a "dyno tune"? Does he mean an ECU software tune?
Interesting there seems to be issues with a couple brands and their tunes. I can't help but wonder if this is all due to the newness of the Hyundai entering this market. Everyone tuning Subaru's, Honda's, Toyota's, BMW's and VAG engines and transmissions have had decades of experience at this point.

Yeah...tuning it on the dyno so it's tailored to your actual car and its mods

It can be a bit nerve wracking to watch as they run the car up, make a few adjustments to ECU tables, run it up again, tweak some more…lather, rinse, repeat.
Obviously disclaimers/releases are signed before beginning.
It’s quite a relief when it’s over.
Optimal experience is dyno tune for WOT optimization coupled with a follow up ‘street’ tune for low/midrange.
Some dynos like a Mustang dyno can load the rollers up to simulate street driving so sort of best of both worlds without traveling to a deserted road in ‘Mexico’ for questionable behavior during a street tune session. Apparently.
If I recall correctly, dyno tune was around $500 back when we did it; took about 4hrs in all, 20 pulls or so.

Well, it was back in 2005 so prices have likely gone up!
When I was messing around with Mustangs a few years later I did a few off-the-shelf mail order tunes; Brenspeed, Bama, Tillman…I think they were sub-$200 for a 3-pak via e-mail. Had to drop a few $ for the handheld SCT Tuner initially to load ‘em though.
