Found the problem.

Weak terminal connection on the coil. not the plug wire.

Never threw a code, didn't miss any other time than WOT 4000 + RPM.

No miss, nothing on the misfire counters,...

We have a unlocking service. Last I checked it was $75

I've never seen a locked tune that wasn't a complete shit show.

Compression checked out.

It could be a wiped cam lobe or some valve train damage from over revving when the clutch exploded. We scoped the cats and they look completely fine. Put a new plug in...

Good explanation.

yep, that one always confused me.

Also some gen 3's will have 12xx in some max torque tables from the factory when the editor only allows 640.

The car came to us not running with a blown up clutch. Like car won't move blown up. I wouldn't be surprised at all if it had a issue before hand. Quite common for people to bring a car for tuning...

I have a 2019 ZL1 brought to me.

The car is a track car and pretty much stock other than a pulley and a rotofab intake. Making around 10psi peak. Which honestly seems a touch low to me but...

I'll bet if you scan it it will have a knock sensor code pending.

It's not a good idea to copy over a bunch of things from a different tune file. Especially from a different type of PCM all together.

I'd address the heater codes. If the o2 isn't heating up properly there is a chance it might run the trims up or down before it actually warms up. This looks like the case here.

I agree.. Something is going on with bank one

That code is a mechanical issue. or wiring. I can't see that being a tune problem.

Credits stay with the cable and not the car.

Some of the early SD OS's keep the MAF from ever working even if you have it setup to do so.

I think you'll see CL fault if there is a MAF failure.. which might be related to the SD OS

Does this have adapter plates on it or does it have a LS3/LSA style head?

This could be injectors.

I had a car earlier this year that audibily knocked HARD with very little timing in it. I tried all sorts of things. Finally came to the conclusion the crate engine the...

This is kind of a rough undertaking for a new tuner.

The 2 Bar OS gives you a blank VE table. You will need to populated the VE OPEN table. The one marked CLOSED isn't used.

You will also...

You have idle timing entirely way to high. I'd shoot for around 18 degrees.. That way when it tries to stall you can go up to 28+ degrees to save an idle dip.

This is often referred to as...

Which file is current? That's a lot to go though.

Do you have a log of it surging/bucking?

It's best practice to set it correctly. The VE table is in reality the same type of unit/number that a gen 4 is but Hptuners uses the displacement value to put that into 0-100%.

05-06 GTO's and...

Nothing looks wrong in the setup.

There is a lot of rough work in the tune. I would start completely over with it.

The map sensor linear and offset are not setup for any map sensor I know...

Thank you very much. I had autos and every other year it seemed like.

You would not be write these into a controller. You have to start off with a GMPP.

Is TPS % returning to zero when this happens?
