the hks is fine but it does lean out the fueling before boost which is why you need a rrfpr to add the extra fuel in. there are only really two routes to go- have the hks fcd and rrpfr get it properly set up and along with the jam actuator run 1bar this is a very basic and limited way to increase the boost level- to be at least reasonable safe i would get a apexi safc just as a basic fuel controller. route two piggy back ecu or standalone- i'm sure you know what they do so no real need to explain- emanage blue does all you need and for the price of a fcd, actuator, rrfpr, safc i know what i would go for. alot of people run 200bhp on fcd's with the supporting essentials so it's up to you.
