If you buy the app, all you do is plug and go. And, yes, they will fine tune YOUR chip, remotely, if needed. No, they will not set up the chip for you, remotely. Buy the app.

Do you want my phone number by pm?

Hi, Chris!

1. It takes no more than five minutes to remove but whether it leaves a trace, who knows, I don’t.

2. As for the Brabus thingy, I’ve no experience with other chips except the Dinan Sport which did nothing for my C450.

have you considered Kleemann also?

Just installed mi e in my GLC43 and initial impression is well worth the money. Curious, does the Racechip override the stock settings (do the stock c, s and s+ still function the same when you are in one of the Race Chip modes)?

I appreciate the response. I got everything hooked up yesterday and took it out for a test drive after activating the Bluetooth app. Need to check today under the hood what the default setting is and whether I need to tweak. My first impression was much more power and acceleration and whenI put it in Sport+ and Race, the power was much more immediate and smooth. I have observed that Sport+ as it exists bone stock, shifted a bit jerky, not smooth. Though not an ECU tune, this appears to be a great compromise of power vs. warranty concern. Once I get the wire loom tucked up like I want, I expect it will be a 5 min. off and on installation. Very well made product, only improvement I would like to see is at the sensor connection. I think the folks at Racechip could continue to refine this to give a more stock-like installation by making the wire loom a more custom fit for each vehicle. Given the length on the connections, I suspect it is more of a one size fits many approach ( which I get from an economics of manufacture standpoint).
