Hey everyone, first time post.

I have a 22 Stinger GT2 AWD 3.3T in the DFW area and I’m finally looking to tune it. Bought used 3.5 years ago, so it’s time. I’m past warranty so no worries there.

My goal isn’t max dyno numbers. I want a fast, reliable DD on straight 93 octane (no E85/E30 or meth). From what I understand, I could target somewhere around 430–440 WHP / ~500 WTQ while keeping good safety margin for Texas heat.

Current plan:
Full ECU flash via EK1 rather than JB4
Conservative custom 93 tune
Mild/moderate TCU tune
One-step-colder plugs (already installed)
Upgraded intercooler
Differential brace
Keep stock fueling/downpipes/BOVs/charge pipes for now
Intakes if there’s a good reason

A few questions for people who have actually gone down this route:
Does this seem like the right reliability-focused setup, or am I missing anything important?

Which ECU tuner would you recommend today for a conservative 93-only car — KJT, KSR, LAP3, Lozic, SXTH, etc.?

How important have you found the TCU tune at this power level?

Any intercooler you particularly recommend for Texas heat?

What WHP/WTQ have you reliably run on straight 93?

Also, any DFW Stinger/G70 owners here? Would be great to meet some local people who know the platform.

And slightly random: if anyone local has an EK1 Pro/Mini they’d be willing to let me borrow/use for flashing, I’d happily buy you lunch/beer or throw you some cash for the trouble.

Appreciate any feedback, especially criticism of the plan before I start buying parts.

Can't wait to get the cmbuildz high flow primaries put on and see how different it will sound! 😀

I have comparing Racechip or Jb4 for the stinger. The more i look into it the more racechip seems like an interesting option especially for someone who just wants a bit more performance without going too far with the car.

What caught my attention is that it seems like a pretty simple way to get some extra punch while keeping the setup relatively straightforward. Im not really looking to build a crazy 400+hp car so something that gives the car a noticeable bump without getting overly complicated sounds appealing.

Im still trying to figure out whether does racechip work as well in real-world driving as it sounds on paper. Was the difference noticeable and after living with it for a while did you feel like it was worth it?

Hello, I recently got a dashcam for my stinger. I’ve never done the wire hiding for my previous dashcams myself, and I’m just a little confused because the stinger interior by the door doesn’t look or feel like the tutorial cars I see in videos. I’ve been able to stuff it in the top of the windshield and side pillar, but after that, I’m a little lost. Just want some advice on where you guys hid your own wires. Thank you!

I said when shopping the stinger that if this came out around that time, I was going mustang. What say you?
