As above i've had a new turbo put on my FRS, after the old one went out in a cloud of smoke! I decided to upgrade a little, so i went for a sorted gt25.

Now this is where i start to get a bit confused, i've been told(by the garage who used Essex Turbos for the turbo work) that this could up the power to around 350 bhp. But they are also saying i need an engine re-map which is gonna cost around £800, is this the case if i'm still using the gt 25? And if so will a blue fin do the job? Any help at all would be greatly appreciated

Thanks
