Went and did it, had the ED30 remapped at Awesome today and that exactly what it is. It made 295bhp and 321ft/lbs of torque(torque at the wheels) on the rollers, bearing in mind the ECU needs to self learn to the map and the car has only done 1200miles I think 300bhp is on the cards.
The midrange surge and top end pull are amazing and its made quick car very very fast.
So I'm a very happy bunny and all I need is a dry day, I had the traction light come on at 70 on the motorway in the rain

Also had cruise control fitted which works as standard but can also switch the map between performance and standard modes.
Can't recommend the remap and Awesome enough.
