I might have to agree. GAD stage 4 turbo upgraded GT63s is only running 10.14@137mph (they claim on 100 octane but that’s likely RON so our equivalent of 95ish). Regardless, that’s not much return on a $35k investment!

what is a JB4? a $30 PCB from China that is reading input (CAN PIDs like fuel trims, octane level, blah blah blah) and that spoofs input (turbos making 21psi but you report to the ECU they are making 19psi so it overboosts an extra 2psi, I think... maybe, don't wanna spread fake news)
You can run different software numbers for sure, but they are pretty similar and the "tuning" related CAN PIDs surely have to be in the same locations or similar. I know you have a Xentry computer thing, you can monitor all of this with that, then sniff the traffic and make your own JB4.
Do you think I am missing something/confused? I might be. But, from a JB4 perspective... read 5-10 parameters, spoof 5-10 numbers on the fly, pretty similar for 2 MED1775 M177 backed "powertrains"

yes but you have to look at it from the context of a JB4

I’m leaning towards keeping car as is and just changing platforms. I don’t think I want to dump another $5k into the car.

What platform were you considering again? You've said before but I forgot.

now imagine spoofing data ( in case with jb4, all parameters are universal, as you said c63 and e63 are same lol) that was configured to do job for one engine to spoof to absolutely different engine hardware, different turbos different compression ratio different max boost (1.2bar for C, 1.3 for E) different gear ratios
well, why i am even surprised, results of jb4 speak for themself. its same as buying universal "racechip" module, which is btw shows same results.
ps you cant beat system so easy as many can think, mercedes new platform seek in tailored tuning.

you are missing one simple thing... jb4 is bad.

I'm confused as to why you think it would be difficult for the JB4 (which connects to your OBD/CAN bus) to do some part number/software number detection, detect if it is E63S or C63s, then tweak the general formulas/parameters. It's still doing wildly the same thing. I wish I had the source code so I could prove it...
But it sounds like we agree overall. It's not a device I would put on my car. I had one on my F10 M5 and it left me stranded in traffic. Took it off, 2 weeks later, entire engine blew. I can't prove it was the JB4 but... just not worth it for me.
