    Hi lads I fitted the ko3s today aswell as a tip BUT if anything it seems to have lost the boost a bit I've checked for leaks but can't find them i put a remapped ecu in the other day and was hitting 15-16psi but im sat at a smooth 12-14 without the feeling of being sucked in to my seat lol I wonder if it's the fact the map was on a ko3? any help is appreciated men

    you'll want to get it mapped buddy, somewhere like R-tech are very good with the k03s on an agu lump.
    you may find the boost will be very spikey aswell

    Youll need to get i mapped, the map like you said is/was setup for a ko3 not a ko3s.

    Audi's work on specified boost rather than raw PSI. So you may find the K03s gives the same power/performance for a low psi due to it being a bigger turbo.

    You should however get some increase in performance but it's likely to be less lag and a harder pull.

    Agreed a new remap on the k03s and you're Fmic will give you the best performance improvement but even so you can safely run the K03s on the map you have.

    Yeh I'm guna ring r-tech Monday and book in I think ur rights the 0-60 feels as good if not better just without the spike of boost I think I had to high expectations and was a little disappointed after 6 hours hard graft lol But I'm sure r-tech will put a grin on my face lol

    Hi guys, finally got a k03s to do the upgrade on my AGU lump. just wondering if you guys have any advice on fitting turbo e.g new gaskets or special tools (part numbers would be great).

    Also thinking about upgraded TIP and De-cat but would i really notice the difference??? i know i need a new tip from a AUQ/AUM engine.

    any advice would be great

    Thanks

    wouldnt the tip be the same? i know theres a slightly larger lip on the turbo (2-3mm diameter) but u could stretch that easy and it has the same outlets as ur engine used to have

    the ebay silicon TIP's are remarkably good quality really, Nick at Rtech actually recommended I buy an ebay job for £45 rather than spend £120+ on a forge!

    Do you have a link to the one you had mate? I'm assuming the price of the forge one is because you are paying for the name?

    No problem mate, I'm assuming it was just a plain TIP though, might get one of the toyosports ones, as their FMIC's are pretty decent from what I've seen/read on here..
