My C450 AMG was totaled . I saved the RaceChip thinking of buying another C450 but ended up with a BMW.
The RaceChip could be reprogrammed and updated for your C450 by calling RaceChip customer support.
I’m selling it for qauter the price that I bought it for.
You’ll increase your Mercedes’s power by 67 HP and 123 ld-ft with the RaceChip GTS Black + Up to +20% MPG.
Choose the throttle response of your needs all the way to race mode with the RaceChip XLR.
Both are the bluetooth versions so you can control the power enhancement manually or very easily using your smartphone and the RaceChip app.
There are detailed online installation manuals “links located below”.
I also have the original manuals with barcodes and serial numbers.
The installation was easy but I still had to call the customer service to enable the unit. The phone support is excellent if you need help with their product.
