Chip Tuning
Does anyone have experience with aftermarket chip tuning? There is a company called RaceChip which claims to have products to increase HP, TQ and MPG in my E350 Cabriolet for around $500. A local speed shop quoted me around $3K (which includes changing manifold, headers, etc., etc.) . I'm only looking for a bit more performance (sports) without having to completely rebuild. Anyone???

I had once, on a 2016 e400 cabrio. Found OE Tuning on this forum, sent them the ECU, they reprogrammed it and I got it back in few days. They stated that there should be a gain from stock 329 to 400 hp. I never had a dyno test done, so those numbers are not confirmed. But the car drove much better after that, and faster. I spent around $1300

Now I want to do it in a 2019 e450, this time a did a deeper research and have same question as you. There are hand held products and reprogramming of the ECU itself. Prices from $250 to $2000, hp gains promised from 50 to 100. I spoke to AMR rep, he offered a handheld tuner for $2K. I asked why is it that much vs the racechip for $750, he stated that the racechip is not doing it properly and can damage the engine. I researched and could find any negative feedback on it though. So Idk
Can someone really explain this whole thing please?

2019 E450 Coupe
I was looking into that too, but what i wonder is that:
1st, Does it void the warranty since your car is brand new-ish?
I have a 2019 E450 coupe and was thinking about the racechip RS also, but GTS version offers 2 year warranty on engine parts which RS version did not.
So does it mean RS could possibly do damages to the engine ? and would MB warranty cover ? i mean you can uninstall but would they find out ?
2nd, Since you oped for Bluetooth adjustment app, does it mess up the center console model selector on your E450 ? does the car gets confuse?
I wonder when i start the car, its on C which is comfort mode, and lets say you set racechip to Race mode, but your car still in confort mode, does in contradict the setting ?
What happen when you set the car mode so sport+ on top of racechip set to race mode ?
My point is that you have setting on racechip at the same time the car itself also have a mode selector, what do you do when you are setting up modes?
Do you stop using center console mode selector and only use racechip selector on bluetooth ? or you still use car mode selector together ?
just want to understand how two mode selector work together on setting different mode.
Thanks !!

Use a reputable tuner like Rennetch, Kleemann and Weistech just to name a few. I do not trust anyone saying $499 for 100 bhp. No way. Stick to what has been around for years and trusted. There are plenty
Rennetch tuned my CL600 and Kleemann tuned my CLK350 & CLK55. Very happy. You want tuners who know what they are doing and not just looking to make power.

Renntech is waaay overpriced - $2240 vs $1195 at lets say OE Tuning. Plus I believe they give you a discount if you mention that you found out about them from here. I had experience with OE Tuning back in may 2017 - same full ECU flash. I sent them the ECU from my 2016 a207. Received it back in around 5 days. Installed and wow it felt so much more sporty! if I floored gas it gave a really sharp kick in the back! Before it was way more smooth. They stated an increase up to 407 hp on 93 aki petrol. I did not verify the power with dyno test, my bad.

2018 E400 Coupe
For my 2018 E400 I just installed the Renntech Stage 1 ECU Chip tune and blow off valve. The sound and power I got were amazing. It's pricey but worth it in my opinion..
