Greddy e-manage Blue. What do you think?

[JDMforever]

Has anyone got any thoughts/comments on this piggyback fuel management system? I'm toying with the idea of putting it in my 2002 SF5 Forester to aid in tuning. Any pros or cons? Love to hear from the gurus before I drop that cash.
Also, is it possible to swap ECUs and install a SG5 ECU in my SF5? Anyone ever tried this?

No one?

The ECU swap wont work if there's the immobilizer built into the CAN. I'm not familiar with the Foresters, so I dont know if this is applicable here.

Instead of the Emanage, why not get a tune on the OEM ECU if applicable (Ecutek or opensource). I'm sure that similar levels of tunability can be done.
