Ok ok ok, i admit it i want the dump valve noise, i have read the thread on dump valve and apart from rhyso's short post it says nothing about the diesel engine, im not interested in performance i'd just like a genuine dump valve noise is this at all possible???

Cheers

Decat = more midrange torque and as you lift of the throttle you get an owl sound :afro:

Ditch excess weight such as the spare tyre and rear seats, go on a diet etc etc

Take off the EGR and inlet manifold and clean them up

And start driving around in nothing but a mankini  :sick:
The owl noise sounds fun though, might start looking for a decat if they are cheapish  :cool:

Correct - just a smoke density test

Rhyso - what system have you got? Possibly looking at getting a new turbo back and piperx panel filter. Would you notice the difference low/mid range with both? Sorry for thread hi-jack but still on the same topic!

Milltek Downpipe and Prospeed (local company) cat back

With just the downpipe I gained around 10bhp through the mid-range and about an extra 20lbs ft torque.  That's with an R-Tech Stage 1 map
