Realizing this is a relatively old thread, and having had the Racechip GTS Black installed for about 2 weeks now - I too feel there is zero difference in power/acceleration compared to stock.
Haven’t had the time to physically uninstall, compare, and reinstall to see if any difference, but playing with the three settings and “off”, the car functions like stock. Everything is connected correctly (i.e., not plugged to O2 plugs or anything like that). Any help appreciated.

On my previous M5, after having the RaceChip for a while, I uninstalled and reinstalled because of service at my dealer. Either during the uninstall or the reinstall, I pulled out one of the wires inside the harness. I did not know what was wrong, I just didn’t have the power I had before. I contacted RaceChip, they sent me a shipping label and off to Germany it went. After about a week and a half, they contacted me to tell me that the RC was fine, but that the wiring harness was damaged. They shipped back my RaceChip with a new wiring harness, and it worked flawlessly. Still using the same module on my new M5 after Ben @ r33_RGSport reprogrammed it for me remotely. Still functioning bulletproof.

That’s a good point about the harness. I’ll check continuity to the pins today.
I haven’t done the physical uninstall since I first plugged the unit in two weeks ago. But correct, I find zero difference in power.

If there was no difference in power from the beginning, it could very well be that inadvertent damage was caused to the harness. I was and am so careful with mine because I was scared of doing exactly what I did, and it still happened.

I’m super careful on connectors, having dealt with VW/Audi ones for years lol. Never actually broken tabs or pins ever - and I wrench a lot on numerous brands.
This was a demo unit I purchased from RG and we didn’t really know length of use previously. The harness actually looked brand new, so not sure if Ben just provided a new harness with the unit or not, but I’ll double check wiring.

Now got me wondering if I’ve got something wrong, too high expectations, or just a lack of awareness (which could definitely be the case.) I can’t say like Reslp or others that I feel such a night and day difference either. It feels fast with and without, It also might be I’m just not pushing it to the limit for the ROI maybe? But for sake of rule out, how do I tell if I’ve damaged the harness?

For what it’s worth, the harness damage was not because of an issue with the unit. It was me that accidentally caused the damage, despite being super careful. Sometimes you can see when a wire is pulled out in the harness, but in my case I could not. RC in Germany ended up having to diagnose it, and I am confident that they were correct since I got that “feeling” it gives again once installing with the new harness. I should also note that, for me, where I felt the difference was in acceleration, and not really anywhere else. Dragy has confirmed that it shaved a few tenths of a second off 0-60 (with and without 1 foot rollout) when I tested it in nearly identical conditions (including DA, ambient temperature, warm up time allowed, and amount of the fuel in the car). Also, are you set to Map 7? Have you confirmed this by checking the display on the RC itself after turning the car on?

I didn’t feel a difference when I first installed the racechip. Took a few days but I think that’s just because it’s performance is felt most above 60+ imo.
Above 60mph and it pulls like hell compared to without the racechip. 0-60 eh not too different. |

Interesting take. While I agree that above 60 is where you feel it, especially at WOT, I can absolutely feel the difference at lower speeds (with hard acceleration) as well.

Yes, upon reinstallation of the unit after a trip to the dealer for an oil change, there was a discernible difference. Just not a gangbuster increase in power that some say they experienced.
