I had a RaceChip GTS on my 2020 Stinger for nearly two years, and it was great. If your car is largely stock it adds a decent chunk of power without any real sacrifice. I never had any problems with it, and I don't know anyone who's had any problems with one.
RaceChip sells an absolute ton of tuning boxes every year, so it's pretty safe to assume that they aren't blowing up cars left and right. If anything, they're tuned extremely conservatively.
The JB4 fanboys love to talk about RaceChip not honouring their warranties, but Burger/JB4 doesn't offer a vehicle warranty full stop, so I don't understand why they think anything to do with warranties is going to win them an argument. If you blow up your car with a JB4 box, who cares right? It's the entire signature on every Burger reply here that if something goes wrong, it's your fault and that they accept no responsibility, yet supposedly the company that backs up their product with an actual warranty is the crappy one? Yeah, makes perfect sense. Just the fact that RaceChip are willing to offer a warranty at all was a huge vote of confidence to me that it was safe.
I've seen representatives from RaceChip answering questions from customers on all sort of forums, but they don't disparage their competition. Burger, on the other hand, loves to go onto forums and talk about how bad RaceChip is, claiming that it will blow up your engine, piss on your corn flakes and molest your cat. Up to a point, that is. As soon as someone asks them to provide evidence that could be measured or used in a court setting, things suddenly go very quiet. Strange. In my eyes this is really unprofessional, dirt-bag behaviour.
Are we supposed to believe that this isn't a business and that these opinions aren't motivated by profit and sales? In reality, the two are barely even competing with each other: RaceChip targets stock cars, and is a safe and easy option. JB4 is designed for modified cars (or at least this is where it can be of benefit, it also works with stock), it has no vehicle warranty, and clearly states that you can accidentally damage your car (and if you do, tough luck). Honestly, the fact that Burger goes out of their way to shit on them is truly baffling. Look at RaceChip's marketing on the Internet. Look at their website. Now go look at Burger Tuning, look at their website (which looks like it was made by a ten-year-old). Tell me who's clearly doing a better job of marketing and being a viable, successful business (which includes not damaging cars and having to pay out for blown engines)?
People don't post here about RaceChip because of the fanboys. Simple as that. Why bother even talking about something when you're going to get a bunch of fanboys telling you how crappy and unsafe it is, yet no-one can actually point out actual cars that have been blown up. This is the same as Coke drinkers crapping on Pepsi, in my opinion. "Watch out, Pepsi rots your teeth!".
I've had a lot of tuned cars, and used a bunch of different products, from RaceChip, EcuTek, Cobb, and soon Lozic. I've never really cared about company reputations, but I can say definitively that I won't be using Burger because of this lack of professionalism, generally adolescent behaviour and shadiness. They seem to provide a good product, and solid customer support, but this is one area where they really fail.
Honestly, this behaviour along with the Tork drama makes me think that tuning companies are run by a bunch of babies. Why don't you guys have some damn dignity.
