I'm Team JB4. I've had mine two years this month and highly recommend it. The company is always updating firmware/making improvements/adding features and the support is among the best, if you need help or experience a glitch. Definitely the best performance bang for the buck. 👍

It sounds crazy but that's the only thing that worked for me, and others, from what I've heard. The problem is they're going to replace it with stuff that's only going to be a temporary fix. You can try the high-speed-stop fix, and that too will only be a temporary solution. Going aftermarket...

I got the rotors from r1concepts.com (best prices but they run out of stock quickly); I went with the elines in silver. The pads came from khartunerz.com; I went with Stoptech, but don't necessarily recommend them (they're powerful but quite dusty). They have plenty of other options though, if...

You probably don't want to read this, because no one really wants to spend their own money to fix an issue on a brand new car. But, if you want to save yourself future headaches AND greatly improve brake performance, you should probably invest in aftermarket rotors and/or pads. I spent 120 bucks...

Even after 2.5 years, I've only been close to another Stinger a handful of times and each time, they ignored me. The only time I've been acknowledged by another one, if you can call it that, was while in Mexico, when I raced a stock GTS and showed him what a jb4-tuned Stinger can do. He didn't...

It's an excellent tuner with a lot of safety built into it to keep you from damaging anything. I'm kinda stubborn and don't follow directions and have changed settings that I probably shouldn't; each time, it simply reverted to stock map to keep me from blowing the engine up. I also never remove...

Oh nothing, it's just that it will be 3 years old in December, so, it'll be time for something new. Nothing out there really jumps out at me so I'm thinking I'll probably end up with a facelifted 2021.

Looks great, and love that exterior color. If I get another Stinger that's definitely the color I want.

Trust me, you want to go with wmi, especially in that FL heat while running Injens. Besides that, if you look at the heaviest hitters on the Dragy board, they all run WMI. It's definitely the way to go and I'd do it myself if I weren't trading soon.

One of the good things about the jb4 is being able to see what's going on in the ecu through datalogs. I just looked at my last log while using LC; there's zero boost until 2200 rpm and throttle doesn't open all the way until 20 mph. So, you're right, LC is basically useless and the burnout...

While I've never tried it at a strip, I've had luck getting RPMs/boost up for a nice RWD burnout by holding the e-brake. If you disable traction and stability control, hold the e-brake while boost builds, then release it when you're ready to launch, it takes off way harder than launch control...

It works across all maps but you really only feel the difference on higher maps and at full throttle.

What IS it with that Telluride. I wonder if it's THAT great, or if Americans are just THAT obsessed with SUVs.

Here you go: https://www.n54tech.com/forums/showthread.php?t=58613 Basically you snip a wire that tells the ECU to limit rpm's at launch, allowing you to build more boost for a better launch.

The most wonderful time of the year....

Working here too. I'm currently in hour 4 and have about 16 more to go. It's pretty dead so I'm dragging. I seriously feel like I need a disco nap. :sleep:

LSD was an option on the 2018 GT. Do you still have your Monroney window sticker? If so it should be listed if yours has it.

I would have gone into that race overly confident and ended up with a bruised ego...lol. I've seen Superbees run and most of them are high 12 second cars. He's put some work into it to get it down to high 11s.
