I agree with Jtech, saty away from air correctors as failure melts engines, the amal valve is perfectly adequate, the std ecu is limited in boost control ,as it is on/off in action, and not load AND throttle angle determined, if you want the best setup for the road, I would get it rolling road mapped, no one including stu can control all the conditions that you can on a rolling road, ie hold rpm/power/speed function to check load sites.
By the time you add on CL, coilpack, AL, ecu,chip, mapping etc you can buy a aftermarlet ecu/loom and mapping, and have many more fucntions, even a triple map costs only £275 where I go.
