running a standard evo 6 engine and turbo in my 4 with apexi avcr boost controller. What is the safe boost to be running this at for optimal performance without comprimising engine failure? oh running uprated fuel pump injectors bc272's and a full remap will be getting done.

I'd go with whatever the person mapping it recommends as it will be their work.
