AMG GTR Tuning Options
I'll just have my thoughts from daily driving for the first bit. Next track day will be in April.
EDIT: mine is a gts not gtr but still thats a fantastic tune.

I would start with a basic tune and go from there. If you ever wanted to go bigger we just charge the difference between stages to upgrade. One other thing you might want to consider before turbos is doing fuel pumps and then blended fuel (E50 etc) Makes great power!

so I have a 2020 GT-R and been having a problem with a stage 1 tune with weistec. Would do pulls on the highway and around 4-6k rpm the car would go into limp mode. Cel would light up but had the car scanned and no codes shows up. Does my TCU need to be tuned?
The Best of Mercedes & AMG
654 hp at the wheel ( catless downpipes and air intake combo)
Those guys at the Cincinnati store know mercedes engines inside out..
owner has a gtr himself (hell magno green) and their top tech has a E63

Also why does EC list stock HP at 552?
STAGE 1
The Eurocharged engineers and calibrators create custom reprogramming of the engine control unit. This ECU software is developed on the dyno and verified with multiple runs and logs. All vehicle safety parameters remain untouched and will function as the manufacturer designed. Like all Eurocharged products, Stage 1 is perfectly safe and reliable for years of worry-free use.- Stock HP552HP

it is a stage 2 tune.. made custom for the car by their engineer. I have no idea what OE offers.. i was specifically looking for a dyno tune and eurocharged are best when it comes to mercedes
542 was wheel hp after installing downpipes and adding air intakes. 665 after the tune. Best decision ever.
When mercedes say the car makes 577 hp it is usually a smaller number that gets to the wheels

One of these days- I will definitely be hitting you up- the reputation you guys have and the info I see you guys helping people with on this site has earned my business. Not that my business means all that and a bag of chips.
And FWIW I agree with the folks saying take the 'upgrades' one step at a time. I live up in the little mountains in the SF Bay area and every weekend someone wraps their expensive car around a tree and in speaking to the volunteer FD rescue folks it seems like a lot of people toss in too much extra power, come up here to test it out and they assume the car will behave identically to the stock spec and they get carried away. At least that is the story they get if the driver/owner is able to speak.
Nam best of luck whatever you decide to go with-
I emailed the ID file from my car on Monday morning and within two hours had a reply with a file for my car based on the modifications I had. I loaded it and took it for a quick drive. The difference is huge!
