Depends what TT you are talking about, the Quattro ones (225) have the K04-022 and the FWD has the K04-001 which is bolt on

If you do a K04-022 you need OEM manifold, downpipe, turbo, TT injectors, TT TIP etc

yep thanks, disregard my email i just stumbled upon all the information you just mentioned + More.

For the curious - K04-022

K04-02x somewhat-official Web Page

TT 225 has K04-023 or 022 turbo...
this does NOT fit a polo.

I have some boost logs. With the stock ecu map - there was no difference between spec & actual boost with the Forge FMIC.
With the stage 1 software - the actual boost is lower then specified over 5000rpm - but I think that could be because the stock turbo can not hold the boost at the required levels above that rpm.
You can see the graphs here -> http://www.vwwatercooled.org.au/f127...tml#post489819

I think that will have more to do with what your tuner does with the "specified" boost map & your modifications. Certainly in back to back testing, the Forge intercooler drops ~ 4psi across the range on K03 & K04 turbo's - widely reported & logged.

If you have modifications outside what your tuner has mapped for, then of course there will be differences. Beware of maps that request more than what the turbo charger can make.
