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.

[@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.

"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.

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.
