Even tho I live in south Wales I have taken my old impreza to surrey rr a few times for power runs and tuning with my old mapper Simon row aka jolly green monster of scoobynet and would not trust many others, great place and guys, built my impreza from a bare block myself and spent a fortune but ended up with a nice 454 bhp with 462 torque at 1.5 bar boost , wish I never sold it now lol
