If it has a turbo, you WILL need engine management for your subie.
As for the 91 octane, you will want to run 93 to run it on the stock ecu. If you cannot get 93 octane, then you will want to use engine management.

Now, ECS sells the Haltech E8 with base maps on them for the Ver 1-6 JDM WRX/STis and there's a company called Greenline in Japan that sells the Ver3-6 Apexi PowerFC (Standalone) at a reasonable rate of $815 shipped and the ver1-2 at the ridiculous price of $1,350.00 shipped.
Hydra does have a plug & play model for the ver 3-6 which you can get from Phil from Element Tuning. Phil has amazing customer support and will go the distance to make sure his customers are satisfied.
Autronic makes standalones that are plug&play for the Ver 3 - Ver 6 as well. They are a little more expensive than the rest, but are apparently one of the best standalone units out there. If you don't believe me, feel free to ask Patr or LightSPD. Both carry the Autronic units.
cars powered by Autronic ECUs have won more rallies in the US than any other brand in the last few years... Hyundai factory team, Subaru factory team (Canada and some of the USA cars), etc. etc.
cars powered by Autronic ECUs have won countless international rallies as well...
Its the best value in a PnP for the wrx, and I've tried *and* tuned them all (GEMS, Motec, Link, etc. etc.)... enough said
