I've changed my air filter.
Picks up a bit quicker. No real major gains though.
A remap might be the option your looking for.

Mines just kit 106k and runs sweet as a nut. These engines are bomb proof if well maintained.
Filter and map should see 145 bhp, which should give you a very noticeable difference.
Maybe get a new engine mount and TIP (if you can find one)
You dont have to worry about changing the TIP on a tdi as it comes with a plastic one, some come with metal, or you can upgrade to metal, soon i weill be getting a full TIP in blue from SFS You only have to worry about a collapsing TIP on a 1.8t petrol
Remap - Serial port software tuning. Changes your fuel mapping to unleash power by removing flat spots.
Filter - Air filter, can be a new panel or an open cone filter.
TIP - Turbo intake pipe, goes between the air box/MAF and the turbo. Can collapse when car gets remapped, so a reinforced silicone one is a good idea.
Engine mount - Stiffens up the mounts of the engine, allowing it less give on take off, improving traction.
I hope this helps...

i thought this only happened to the 1.8t 225
how easy are engine mounts to change? are there any engine stabilisers? my engine is quite wobbly, especially on the passengers side. What bout the pipe from the intercooler up?
