Thats interesting, Might consider doing this before upgrading
vrs alex has a hybrid k04 with wmi iirc
Who would do the custom map after the install?
GIAC also have a hybrid extreme file.There are many other things to consider if you are thinking of going for a hybrid K04 upgrade. Fuelling is one of them. The "in-tank" low pressure fuel pump need uprating (internals like the HPFP) and also RS4 injectors (you can use OEM K04, but they are limited). All these add up.
