TESTING TUNING BOXES! Are they any good? DARKSIDE DEVELOPMENTS

So we get asked all the time about "XX Tuning box makes X power so why does a custom tune make the same? or less? or only a tiny bit more?" so we decided to do an unbiased test, with the intention of offering tuning boxes to our customers looking for that easily removable power adder!
Please stay tuned in for a follow up episode with our solution to all of your problems!
This was filmed around 12 months ago and was not, and still is not, intended to start a war or slagging match between any companies. These 3 boxes were chosen as the top 3 on Google searches, so likely the most popular 3.
We are entitled to our own opinion and so are people running these boxes or selling them but rest assured no bending, twisting or altering of the figures to produce a sensationalised video has occurred.
Short summary if you want more power, these expensive tuning boxes are way overpriced for the gains you get. We have had countless customers arrive with these boxes and be rather upset with the gains when tested on our dyno - www.darksidedevelopments.co.u...
Our Powergate solution video coming soon:

Thank you so much for this video. Very thorough explanation of the differences between tuning boxes and remaps. Have been tempted in the past to go for a tuning box, mainly because of the simplicity of fitting the box, but as your video shows I think you're much better off leaving tuning to the experts such as yourselves. Thanks again. Cheers, Jon.

Why anyone would dislike this video is beyond me. Ran a racechip ultimate on my Amarok 5 years ago, then “serial condition.” Sent it back for my refund within a week. Only change I noted was more exhaust smoke. Back then, there weren’t any real tuning options in my country, but now we have a local revo dealer. Greetings from Trinidad, WI. The local VW scene is very keen on your Amarok videos.

Massive balls for doing this with transparency. Well done. Custom remaps will win every time, but I had a great result from a dtuk box a few years ago on a saab 93.

Darkside hope you don't mind me asking, do you have a preference on diesel engines ? For example Mercedes, Bmw or Audi v6 diesels ? Looking at a few personally, always had vag but i know the Bmw 6 cylinder is fantastic, probably looking at moderate tuning based on what you have reccomended in your videos 👌 cheers dude much appreciated

[@AGChiptuning]

Your 100% correct about most these companies claiming higher figures than a good ECU tune. Customers believe it though.

[@MrAlfajames]

I've had 4 bluespark tuning boxes on 4 different cars, petrol and diesel so far and although I've never had them on the dyno so I can't say about peak power I can 100% say they improved low down power and boost response on every one of the cars or I wouldn't have bought another. I have done the same route to work for years and as an example on my car with the last box (jaguar xj 3.0 diesel) the difference with the box fitted was very obvious. There's a steep hill on the A23 called Handcross Hill and on cruise control with no box at 65mph the car had to drop a gear, with the box on it never did and I tested this multiple times. The best part was when I sold the cars I removed the boxes and either got them retuned for the next car or sold them on

[@muffindell]

I agree that the Bluespark box does work very well, the company also has great after service back up; but the main thing that sold it to me was that Bluespark also remap cars on their Dyno in the traditional way so have a great knowledge base for both ways of tuning without bias

Great video again Team Darkside! Looking forward to the next video. Would you ever think about creating your own piggyback or tuning box that would allow you to do remote tuning or similar worldwide? Chosen resellers workshops logging pre and post tune for R&R. Also, just a suggestion for another video, what about a video explaining darkside's beginning up until now? Explaining where you came from professionally, the family side of it with SRS, and your technical backgrounds. Maybe a quick overview of the present team? A look at staff projects? I'm guessing you and your brothers were vw or audi technicians or apprentices originally? I think it would be good to show more of who you guys are, more than just "Reet then Ryan" (nothing wrong with you Ryan!). Cheers again guys!

[@link6032]

Great video, thanks for this. DTUK have always been hit and miss, they get really stroppy when you question them, and even return a box based on performance. I fitted one of their boxes and the engine colling fan kept running after turning the car off, it was like the car was always trying to perform a dpf regeneration. Anyway, sent it back and got a very very cold response.

This video says everything what need to know. Great job! Just a quick suggestion for next video idea. I would like to see a comparison between a custom map what you do and a remap which done by uploading a already tuned map for example made by Alientech. As you know they make the same map to the car which has done only 45k and 200k as well as long as it has a same software. I guess many people will be interested in seeing this. Keep up a good work guys!

Very interesting video and I wish I could of used this info 3 years ago. My Mk7 Golf GTD (CUNA, 184bhp) had a DTUK CRD3+ box on. It dynoed at 198bhp when quoting 240bhp (240bhp is the holy grail of custom maps, most get 235). The Golf actually blew an injector after 2k miles (engine was on 11k). Always wanted to pin it on the box but had no proof. Andrew and the goons at DTUK are awful and some practices are illegal. They'll be your best friend and reply within seconds up until they get your money, after that they'll outright ignore you and used to (not sure if they still do) charge 20% restock fee if you return the box which would work out to around £90 of the unit you sampled. Biggest mistake I ever had, made the frequent slips into limp mode under full throttle seem like normal. (Edit: The mobile app, DTE Powercontrol that they use also requires location, storage and phone call permissions to work on Android... Why?)

Tried a DTUK box on my mk7 Golf R. Didn’t feel any better to be honest and ended up going into limp mode after a month, so I took it straight off. Luckily I scanned the car with VCDS before it went in for a service, there was all sorts of fault codes stored. So much for their main marketing pitches, the fact they are undetectable which in my case was absolute rubbish.

[@MuzzyT]

Put a racechip on my A1 and I feel as though its severely reduced the life of my engine. It made the engine knock (with correct fuel), was overboosting and even after I took it off, over took a car on 2 different occasions and put my car in to limp mode + engine light. Would never use one again. Complete trash. Its an engine breaker.

[@wildazme2006]

When using a racechip you have to upgrade your plugs, if you didn't that's the problem.

I can see the difficulty you guys having telling people the truth without getting sued by those companies, well appreciated and most of us anyway we were thinking the same but now we know for sure because you did dyno more than one tunning boxes and on top of that that car performed way higher with the remap. One might be wrong but since none of them touched the "claimed power" it's clear they never do and it's just advertising. Anyone reading this comment and looking for a solution , it's clear now that remap is the only right thing to do. Good job Darkside Dev.

[@williamoakes664]

Great video 🙏🏻...proves my experience...I’ve tried boxes but they’re all gimmicks by comparison to the proper map. My t5 (1.9) van, bmw 330d f31 have custom maps both proving true results and stark differences in performance (torque mainly on the van and explosive results on the 330d👌🏻329bhp 650nm...just needs an lsd really). Same principal applies with bikes...I’ve just put a full system on my Gsxr 1000 k5 and although the seller has given me an appropriate map for my PC3 it’ll just be the Dynojet preset with options applied. The bikes going to a tuner on Tuesday for a full custom RR tuned map. It’s more expense but I’d rather it was running absolutely spot on.......and furthermore (the other very key point I’d like to state that your comparison didn’t mention) by taking the bike to a specialist allows him/you to give it a look over and check everything’s in good order before turning the wick up....this is invaluable by comparison to the box ......having a healthy gain as opposed to breaking your pride and joy is worth more in the first place.

[@hardcoretam]

The only idea of "tuning boxes" i liked was ones i seen somewhere, where your car can have a custom rolling road remap set up, but it's stored on the box instead of the ECU. The only other time i'd consider a tuning box is on the old Transit Connects, or the older Vauxhall engines where the boxes increased fueling mainly, then boost was done with a manual boost controller. I feel for the vast majority of the time, a generic non tailored, non rolling road remap is still probably better than a tuning box on most modern diesels. I feel if you have some simple bolt on mods like a turbo back exhaust, upgraded intercooler, it's worth getting a custom tailored map on a rolling road when possible.

I have a RaceChip installed on my F40 M135i and it's definitely making a difference in my case. There is now no performance gap between my car and a stock M140i all the way up to 156mph (we were absolutely side by side each time we tried), which there certainly is with a standard F40 M135i (306bhp plays, what, 335bhp?). These new generation BMWs appear very difficult to remap, either though OBD or a bench tune, so until that's better understood, this might be one of few options.

Got a Torquit chip on a 79 series V8 diesel, been on for over a year, really happy with it. Run it in the lowest setting, gives me the extra power I was looking for. EGT's have remained around the same, so engine dosen't seem too stressed. Time will tell I guess?

Can't wait to see your version of tuning box! This reminds me to Gale Banks.

Great review, I’d like to see how the JB4 compares as lots of reviews by owners who report a big difference in the drive and even shave off their 0-60 time, but be interesting what power these actually add.

Jb4 are brilliant and reliable. Was the only thing I had to tune my golf R fur a while,
