Anyone out there have experience with the S chip? I'm looking to get my 2019 C43 at or just over 400hp. The S chip says up to 37 hp and that is not very definitive. I'm fine with going up to the RS chip to get me there if that is a better option. I'm not interested in the JB4 since the RaceChop install seems more straightforward and I'm not looking for a big bump up.

Thanks

Not interested in making any exhaust modifications.

OP, I would consider a reliable Dinan D440-0035 chip, good for up to 40hp/tq at under $250.

Thanks! I will check it out.

I have spoken to someone who has a gle 43 who had the racechip + (is what he called it) done at the local Mercedes dealership and it is pushing 420hp without any other modifications. Cost was around 1,000 total.

Dinan does the same for less than 1/4 of the cost and as a 5 minutes DYI. It also looks a lot better (with a single connection with OEM like wire/harness) under the hood without Racechip's multiple (2 to 3 connections, depending on the model selected) thick hoses.

Why not get a JB4 or Eurocharged tune? You can swap back to stock in a few min or less if warranty is the concern.

Dont put that racechip crap on a mercedes. Get a real tune.

I live in Phoenix and spoke to the guys at https://www.goodspeedperformance.com/ in Scottsdale AZ. These guys have a good reputation. They say it is a solid chip. Of course, they mentioned the JB4 and I told them that it is more punch than I need. They will sell it to me for the same price I can get on the Dinan website. I will have them do the install for the one hour charge. I will post how I like it.

Thanks for all the feedback.

I've been running a RaceChip in our 2017 C43 Sedan for over 5 years and my experience is that it's a fine, high-quality product that gives good performance benefits. Zero issues ... just works and works well. Run some searches and you'll find various postings I've done related to its operation (and they still all apply, after all this time).
