    Audi A6 Avant 2.5 V6 TDI Quattro

    Thats a very nice fix and a nice dyno too. I have not been able to give my car to the tuners much this year as i am now driving 5-600 miles a week, and have run out of spare money for tuning, but will see if i can get the pop pressures altered.

    Audi A6 Avant 2.5 V6 TDI Quattro

    Sorry not been on here for ages. Yes i have the idle shudder, but it varies, sometimes worse than others. Fortunately with most of my driving (Falmouth to heathrow commute) i don't find myself at idle very often.

    Audi A6 Avant 2.5 V6 TDI Quattro

    Hmm. Celtic didn't have a lot of joy. They said that the exhaust is almost too free breathing for the turbo now, a lack of back pressure at low engine speeds is not helping the turbo spool up (apparently VNT need back pressure to help spooling?). I'd welcome some feedback on this. I need to sort...

    You're in Devon, Plymouth is in, er, Devon. How far away are you? It isn't exactly around the corner from me either but choices in Cornwall are kind of limited.

    The most powerful 2.5tdi V6

    I am arranging to go back into celtic to see if the 3" exhaust takes us any further. If with bigger nozzles, hybrid turbo and a remap we get 266hp, basically bolt on extras, surely someone who into heavy modification can get further.

Need to get another remap. I do have silencers, my wife...

    Audi A6 Avant 2.5 V6 TDI Quattro

    Sorry, wasn't paying attention for the last few days. Booked in for week on Thursday. I looked at the double tailpipes but decided it was too much, just having a single straight slightly oval tailpipe each side. You want 2 downpipes? I'll ask him if he wants to do it. Maybe we'll get a bulk...

    Audi A6 Avant 2.5 V6 TDI Quattro

    Proposal Take the turbo off to get access to the down pipe. To make sure the flange properly mated to the turbo ,cut the flange off the original pipe to use as the end of the new one. He reckons this cuts down on problems with differential expansion rates between the stainless steel and the...
