I've been dabbling with various tunes over the past year, Renntech HHT, JB4, Solo CPC & TCU. I was able to hit 10s consistently with all the above, but wanted to try another flash at home tuner with file switching capabilities. So I ended going with AMR performance. I have a facelift, so there aren't many flash by yourself options like the pre-facelift. Renntech was the first with their HHT, and now AMR.
Summary of results with fuel and hardware. All stage 1, stock turbos and stock DPs:
I just did a Stage 2 Eurocharged and I have been very impressed. I haven't gotten a good run in yet because I am spinning too much off the line and sometimes when it shifts to 2nd gear. I need tires pretty badly...lol...What tires are you on?
EC says I don't need the TCU tune since the 2019's don't have the CPC.

I'm on Michelin Pilot Sport 4S, I highly recommend them. I was still able to get 1.6x 60ft on the stock Continentals, but now I can hit 1.59 60ft with the MPS4s. And they last a lot longer too with no crabbing.

That has always been my go-to tire. For some reason, my current set hasn't been as good as the sets I have had in the past. They spun, while brand new, on a stock tune. My P-Zeros seemed better on this car than the PS4S but it was the opposite on my SQ5 and my GLE63s.
I am getting a lot more mileage on the PS4S which tells me they may not be as soft. I don't know...it seems weird. I still have crabbing with the PS4S once they get a little worn. I have brand new fronts and the crabbing is gone but it will come right back. It doesn't bother me.
How do these aftermarket tunes impact your MB warranty?
If you tune, and if you have a powertrainissue during your warranty period...you may be held responsible for causing the issue. In reality, the tune may not have had anything to do with the powertrain issue. Proving the cause of the issue becomes very gray and is the responsibility of MB. Depending on the issue, which way do you think their experts will lean? If you tune, you should assume you have crossed out the language covering the powertrain warranty. The good news is that you still have coverage on everything else that is not powertrain related.

Thanks for the quick reply. I figured as much. For now, maybe best to keep warranty instead of tuning. Once warranty has expired, I will have it tuned. Cheers.

Or, buy an older GLC63 for tunning... (Baller status) haha

I have always refused to use a tuner that doesn't offer their own warranty. There are many great tuners out there but there are also some hacks. I think if it is a reputable tuner, then they stand behind their tune.
Renntech and Eurocharged offer substantial coverage, on your motor is something goes wrong. Sure, they are a little less aggressive than some other tuners out there but their goal is to provide a safe tune that they stand behind.
You first tested the tune only. Did you drive it enough to notice any differences in shifting as the stock TCU/CPC held back the power?
Summary of results with fuel and hardware. All stage 1, stock turbos and stock DPs: 1) 91 Oct, stock hardware, stock CPC (1/4 mile, 0-60)11.36@119mph, 3.25s 2) 93 Oct, stock hardware, TCU, CPC11.08@122mph, 3.05s
When I had the Renntech tune the CPC made a huge difference. I ran a 12.0 quarter on tune only, then a 11.25 right after the CPC install. The AMR tune is a lot more substantial by itself so adding back the CPC definitely made it perform better, but obviously not as much as with the Renntech. I've also ran the CPC only, stock tune, and I could feel the difference, felt almost as good as a stage 1 tune. I've also ran TCU only on a stock tune and it's very overkill, feels like a race clutch on a stock motor, you can really feel the higher clamping pressures. If you want more than ECU only, then I highly recommend getting all 3, ECU/CPC/TCU, they all work together very well.
New here!
Moving from an Alfa Romeo Giulia Quadrifoglio to a 2019 AMG GLC63 4MATIC
I reached a point where I could not make the Quadrifoglio any faster without a lot of money - and even so, I could never get into the low 10s (1/4 mile) with the Quadrifoglio no matter what.
Definitely want a solid tune for the GLC63. Shooting for 10.5 at least but would love to go faster than that even.
I see a reference to the term "TCU" - what is that?
I'm considering the Weistec ECU tune, CPC, and maybe their filters too.
Any tuning advice is welcomed & appreciated! Thanks all!!

GLCya63 has about the fastest one on here. His turner is one of the most aggressive and with DPs, he might get yo a 10.5 but that is going to be about all you can get out of these cars.
KingMonkeyJr tried about everything including new turbos and fuel systems but got where he still couldn't get enough fuel to it to make it run right.
He tried several tuners and said that Weistec was the worst and EuroCharged was the best at helping him try to achieve his goals.
I also went EC. My car is a beast but I can't prove it because I spin all the way to the second gear shift. Still hitting a 3.2 - 3.3 with the spinning.

Well, I guess it depends on how much money you want to throw at it. If you spend $15K on turbos and downpipes and intake like this dude from Dubai, you can run a 9.99
But thanks for the info. I’ll check into EuroCharged. Appreciate it!

When you say CPC, do you mean the one that Weistec sells? Or another one? Thanks much.
I’m probably going with EuroCharged and their Stage1 Tune, plus their TCU tune. They say that will get me up to 639HP/615TQ, not to mention the gains of the TCU removing the torque limitations in 1st-3rd gear. Then I’m having a methanol injection kit added, which in the heat of Texas is a good thing anyway. That can add up to 50HP under the right circumstances. The shop that is installing the Meth injection kit will do a dyno for me afterward, so I will have some dyno numbers to show.
I’m down to move this thing up to nearly 700HP for a little under $6K. That’s a bargain in my books!
Should get me near my 10.5 quarter mile time. . Draggy will tell the story!
Thanks all for the suggestions!

I think 10.7x - 10.6x is the fastest you can hit with stock turbos. Anything faster will need at least a set of hybrid turbos and proper tune. Sub 10.5x is larger turbos like pure 1000 or weistec W.4s, upgraded fuel, meth. Like some have said previously, all about $$$. I have a few more mods coming soon, just need the time to install everything.

Totally agree. It still amazes me that we are talking about 10's, on a daily driver SUV. Back in the day, a 12 second street car was a very special car.
My first Dragy runs. Here was my best 0-60 today, the week before getting tuned. Notice the 0-30mph number of 1.35 seconds. The best I ever got in the Alfa Romeo Quadrifoglio I traded in was 1.69 seconds. That AWD grip matters!!!
Next week? MUCH FASTER - I hope! First Dragy run
