    I am sure tuning wise first come will not be disappointed!
    So are you are going to start from scratch on other Allroad?

    Technically yes, i will have to start from scratch but already i find differences which makes me want to keep the old one ! For starters, the BAU engine in the final/limited edition allroads is using a lesser pump, it does not have the 3 plunger head as the early allroads, which i was suspecting due to slight differences: early allroad has full alloy intercooler, later has plastic end caps, early has bigger nozzles, later are smaller but atomize better. Early have cruder/fewer maps in the ECU (512Kb eeprom memory), later have 1Mb eeprom so more sophisticated maps !
    Good thing with the later is that's manual gearbox and never been towed with it, however gearbox is not as sleek as the early car despite being lower mileage + it's been kept by the seaside which means the underside is a little bit rusty when my old allroad is pristine underneath !
    Also the early model is better equipped: front/rear parking sensors, the suspension has been rebuilt, new rear airbags, solid track rod ends (makes for a very precise steering with loads of feedback), front/rear antirol bars and much more...It will take me weeks to bring the new car to the same level as the old one but hey, it's a new car, should be better, no ?!

    Made some alloy hardpipes for the "new" allroad, had to make a few as i have a couple of friends with same cars/engines. I kept blowing boost hoses and they are very expensive from dealer- the new alloy ones won't break anymore... So far the new car behaves really well, there's a couple of quirks with the self leveling suspension but i have a whole spare allroad for parts if needed.
    Spent a lot of money on a Thermal Arc AC/DC welder and pure gas to weld alloy, had a TIG before but that could not do alloy...

    Swapped the intercooler i had on fjtwelve old a6 and fitted it to the "new" allroad along with a 4 Bar map sensor and uprated Mikalor hose clamps then mapped the car to suit the gt2052 turbo, it goes really well and no lag whatsoever ! next on the cards is either a hybrid 2266 as i had on the 300Bhp a6 or a GTB2260vk as i still have a few in the garage ! Next is to swap some of the parts of my old allroad then decide which to keep !
    The BAU engine in this allroad has a very rare block 2.9L, every other one i have seen has a different cast marking apart from very few early AFB engines which had a full 3L block yet still sold as 2.5 !

    After tweaking the map and adjusting the actuator/stop screw to get turbo to spool half decent i am at a point where i do like the car ! It has far more power than the old a6 i had from fjtwelve ! If i find time i will take it to AMD in Essex to get it on a rolling road... Goes like mad but i have fuel shortage, had same issue with the engine shutting down on a hard pull, the fuel lines just cannot cope with the fuel demand ! Had a bit of a "in gear" drag race with a b7 rs4 cabriolet whilst towing my empty trailer and is fair to say that the rs4 stood no chance from 30 to 70 Mph ! Sadly i am getting rid of the car, one of my cousins offered me money for the car albeit in standard form...
