protune is what we call a tune by a professional on a load dyno over here in north america. same thing you call a tune over there.
you should be around 325whp on your 98ron fuel. you could top 300kw/400whp if you switch to E85. you definitely need to fix that lean issue before you detonate your engine in half.
haltech is great. they have plug and play ecu's for the EJ207. best on the market in my opinion http://www.haltech.com/product/plati...es/subaru-wrx/
if you need a tune, i can recommend these places but not sure if they tun on ECU Tek. honestly it might be worth your efforts to cut your losses and switch ecu's. everyone i know personally has hated the ECU Tek system and got rid of it shortly after purchase.

there are probably hundreds more, but if these guys have made an impact on me way over here in canada, they must be doing something right.
