Very nice mate, the Evo 10's respond very well to modifications as well and stock engines are strong & good for about 500 BHP. That 4B11 engine is simply awesome, mate of mine has an FQ300 and with just a 3" exhaust, induction kit, upped boost and a remap it was seeing 420BHP and similar torque on dyno dynamics rollers. However that's in for a rebuild now because he's wanting silly power (600+ BHP).
Hope you enjoy it mate, Evos are good cars, but they are made more for the twisties than straight line speed.
Just a quick note, if you get it remapped with ECUtek they will inform Mitsi and that will void your warranty, quick heads up on that one.
The reason they inform them is because the factory UK Evo 10 ECU's are locked and ECUtek dealers get an unlock code via ECUtek from Mitsi, hence they always know. However there are other ways to map them without Mitsi ever knowing if you want to retain the factory warranty until it runs out. Actually, being an 08 car there won't be any factory warranty left, so no worries on that front.
