If you swap the loom, ecu, key and clocks you may need the MAF sensor aswell as these differ from engine code and may not work with a different setup...
The AUQ engines came in mk4 aniversary golfs which have 180bhp, TT's, etc.
They came with the slightly larger, slightly better k03 sport turbo which doesn't die off towards the top of the rev range like the k03.
The injectors are also slightly larger over those on the 150 engines.
The AGU engine has the 'large port' head. These are commonly used when going past the k0x turbo's giving better results @ 300bhp. the other engine codes seem to give better results when using k03/k03s/k04 turbo based setups.
A friend of mine has s AGU 150 engine running the k03 with a few other mods on the OE management and he says Jabbasport mapped it to 220bhp.
I was told with the k03s on OE management you can get 230bhp and on standalone management you can squeeze that up to 240bhp before a turbo swap is needed.
