2022 GLC63S Coupe Ordered
My plans are:
- Renntech ECU+ Module
- Renntech BOV Adapter
- ModalWorks High Flow Intake System (Eventuri looks awesome, but sealed setups don't produce as much sound from my past experience & any hp increase/decrease is negligible between noth systems most likely & the hood will be closed 99.999% of the time anyway - Plus $3k vs. $1k)
- Renntech Suspension Module
- Vossen HF-5 22x9.5/22x10.5
I was considering downpipes, but typically it's labor intensive to get the stockers out in case I'd have to put it back on for warranty purpose. I don't think I'll do those. I was reading up on the TCU & CPC tunes, but Renntech unfortunately doesn't offer this. Are there any other tuners out there that are "undetectable" so to say, although I know that it's not fool proof & if catastrophic failure occurs...well I'm sure they can find out it was tuned. My dealer is "Renntech friendly" so to say, so I don't have much worry about the reliability or warranty going with Renntech, but are tuners like EC, DME, Weistec, AMR, etc. similar in "undetectability" like Renntech is, or is there something proprietary there that no one else has? Also, I heard that Renntech will soon be selling warranties with their stuff, so that might be some ncie piece of mind depending on pricing. I would love to go with AMR to unlock the torque limitations & shift points, etc. BUT my gf will be driving it primarily, so I think a few tenths of a second quicker doesn't outweigh maintaining stock-like reliability & warranty (or at least peace of mind).
Any feedback is greatly appreciated. Also, any little interior/exterior mods/accessories that are aimed towards OEM+ appearance... hit me with them. Thanks & look forward to receiving it in December/January (build date set for October).


-Full PPF / Ceramic coating - Totally worth every penny and would do it again
-Eurocharged Stage 2 ECU, TCU and CPC tune - Since Oct - No issues, really opened the car up and turned it into a monster
-ModalWorks intake - CF looks amazing, not sure I would notice much of a difference without the tune but have noticed my 60+ acceleration subtle improvements
-Remote coding to add in Race Mode and a few other options that were only available on Euro spec or S model
-Remote lowering from a member on here, super easy, definitely recommend
-New brake pads - Hated the brake dust so much switched to some ceramic pads that I bought on Rockstar Auto - Posi brake pads - Haven't had any issues or noticed a decline in performance
-Chrome delete - Had the grill and door handles wrapped in black, love the look
-Painted brake calipers to match body color
Know quite a few other owners who have done an ethanol tune and are pushing way more power, few guys out there have done Pure turbo upgrades as well... this thing can turn into a savage beast.
