I dissagree.....If the only way to know was to live map then turbo selection would be trial and error....with a live map inbetween each swap. Or a selection based on other peoples trial I suppose.

I need to know the boost required @ 40-42Lbs of airflow for a YB....someone must know So that I can figure out where abouts on the compressor map I am for the turbo I think is right for me.

I'm looking at this turbo to deliver the power....


Is this going to be capable of delivering the air I need to for 400-420bhp?

Ohh I forgot to say it'll be externally gated with a tial gate
