Safety first... This is why I let darkside tune my car. I'd rather see genuine safe power, than a big headline figure that will melt an engine. Nice work

[@adamkhan5274]

Try a UR quattro 20v. They run hot.

[@Jeroensgambling]

Thats primarily because of the emissions. Engines are heavily downtuned sort of say to keep up with emission. Once you uncork that, well, you start having serious potential.

350bhp as standard is good as is but this looks to have huge potential

[@FPVForLife]

Huge potential? No, well yes maybe. If there wouldn't be any of this emissions crap. He even said it in the video, they are pushed hard straight from the factory. Boost, IAT (100°), EGTs and back pressure from hell because of this Euro 6 cat/dpf/scr bullshit. I bet the back pressure could be measured in Bar. And then imagine what is going on before the turbos, just to get them spooling... rediculous. And all the crap getting past your pistons because of that. The oil is pretty much done after a few thousand kms. Don't believe me? Go ahead and do a oil analysis. Really everything turns to shit.

[@archiewade3422]

best exhaust system to get to get my diesel sounding similar to this??

[@danielmarshall4587]

"although the customer weren't interested in messing about too much" they then saw 380HP .....and, OH DEAR power corrupts and total power is cool. Many folk have a long face regarding Audi's use of diesel engines in their "S" cars, personaly I was lucy enough to have an RS2 and yes it was smiles all round apart from 18MPG. Years later I've now got an A4 B7 (I think is the generation) with the 3.0tdi which I am led to believe has a "re-map" on it and I'm often laughing my arse off & 30MPG. AND ONE DAY....( overtime permiting) I'll be coming to use your services gentlemen, 'till then all the best and every continued success and another thank you.

[@RealGX]

Forget about tuning your B7 the BV50 turbo and injectors are made of chocolate, better to get a B8 and start from there.

[@danielmarshall4587]

@@RealGX oh I'll need a BIG income increase before any tuning takes place it needs a new clutch, new rear light clusters... new, fuck me the list goes on. Though it has over 190K on the clap'o'meter and is still rolling so I don't want to chance my arm too far. It spews MASSIVE clouds of VAG cancer-death from the exhausts when I boot it which is the reason people believe it's had a re-map though I've not had it on a rolling road to check. Hopefully soon I'll get some overtime/LOTTO win and get it to these good Folk in Barnsley.

@G.Warren have them remote tune your MK7 while it’s on the rollers here in the States. I’ve been trying to find the right A7 3.0 TDI to turn into a comfortable highway monster that will make 11 second passes while getting 40+ MPG highway. Ventilated seats, 11 second quarter mile, 400+ horsepower, and one of Audi’s best looking body styles.

[@93ChayZ]

Man I am dedass bummed the US will never get the B9 S4 TDI… that torque the better mpg… Still love my gas powered B9 S4 but woulda def bought the TDI in a heartbeat if it was available…

[@ENC81]

Hi from Sweden, nice work you guys put overall , great explanations and knowledge 👍🏻. In have one question about new Audi 3.0 (45TDI) engines particularly ones that I have and considering to tune in to stage 1 . Here in Sweden tuners can tune this engine up to 350-360 hp 🤯. What’s your thoughts on that ? It’s this ok with all oem parts or there Is need for more stuff to do ,to achieve this performance, Tnx !!!

[@DarksideDevelopments]

the turbo is too small for those figures on the normal 45 engine!

[@eddiemichael4333]

Can someone make a Machine that can copy these smart brains and computers of these guys so i can tune my tdi cars?:))

[@derrelcarter9401]

Have you ever tried thermal dispersment coatings on an intercooler on any of your jobs? I have seen them used successfully on some undersized OEM factory a/c condensers in limited available space on some 3/4 & 1 ton diesel trucks that increased the performance of the factory units enough so the problems pretty much went away, except around 116+ F ambient temps?

[@DarksideDevelopments]

We haven't but it could be something we try in the future

[@stevenwhitcher2851]

So if you wanted to up the power in a safe way, you mentioned the intercooler, if money wasn't an issue what would you recommend to do to the car, size turbo, exhaust intake??, what to do without changing internals

Well a gtb2260vklr will make 300-330hp on a 16v Z19DTH, so I don't see why a modern VAG 2.0 with a gtd2363 wouldn't make around 390hp reliably like in this video. That's right about what I'd expect from a bigger compressor coupled with a 15 year newer engine design.
