@@DarksideDevelopments i saw in one of your videos that you’d adjust the airbox, isnt it better to take just an rs6/rs7 airbox and put it on there as its slightly bigger has better volume, and has the holes drilled in already. And it fits without moddification

[@easyaussietarget3355]

Awesome!!!!

[@johnjerrehian4642]

I was surprised that there was only a 2 HP difference after all that. A decent software upgrade seems to be the most economical move on these diesels. Improved my TRQ and HP nicely on my 2014 Audi 3.0 TDI

[@DarksideDevelopments]

It would have made more of a difference if the stock DPF was blocked more but you are still only regaining the lost bhp rather than gaining more by removing it. A remap is most definitely the best bhp for £

[@johnjerrehian4642]

@@DarksideDevelopments I agree. Then the difference could have been huge. How did you find things with the air box? I saw where you were talking about opening up the front and putting the space with holes, (which to me would have been easier just to drill a few holes). Notice anything? I kept stock airbox but am using a Pipercross filter. Really no difference that I can tell

[@DarksideDevelopments]

@@johnjerrehian4642 We have not modded the airbox yet but we did remove the airbox completely while on the dyno and this made no difference. The holes or vent may have more of an effect on the road (there must be a reason the RS models have this as standard)

[@johnjerrehian4642]

@@DarksideDevelopments Great info. Thank you! I was interested to see if the additional air, (from the holes like the RS models) made a difference. However, the displacement of those engines are typically larger and under WOT may need more air than the standard airbox can deliver- Hence the holes. Maybe the 3.0 TDI's are getting all the air they need via standard airbox? Love to hear what you think as well as any difference with the holes in the airbox, (besides noise). Plus, your TDI produces a lot more power than mine. Stk form US 240 HP 428 TRQ. Race Chip on 7- 283 HP and 515 TRQ per Race Chip.

I have seen alot of people just replace the airbox with an c7 Rs6/7 box. Looking to make a 500-550hp build but not much info on it in UK. There are few companies based in Eastern Europe that have gone hybrid route and achieved these numbers but its hard to find detailed info on what has been modified and upgraded. Can't wait for your next update. Hopefully the turbo issues is resolved.

Hi, my car had a remap and the guy claimed that I could get 195bhp from my engine. But he also said if he did a cut gut and shut on the DPF, there was another map he could put on. This map without the DPF would give me 215bhp. Does that sound right on my engine that is a 143bhp 2.0tdi A4 engine code CAGA? I read somewhere that the most you should push out of it is around 180bhp. Anything over that is over doing it and risky. Is that true? Very good video by the way, always interesting thanks 👍
