    Why is that?, certainly the old arguement point of Superchargers vs. Turbos was the Turbo never made good low down boost, but you are saying not to build boost too soon or it will rob power. Just curious....

    You will feel it....It is all related to the drive pressure created by this turbo. It robs you of power, makes your EGT's raise...and is in general a bad idea. Just play with it. You will see what I mean. You will not hurt anything, but don't build 30psi at 800rpm...it is worthless. Keep the psi around 30 at WOT with a larger tune and you will be doing great. Another thing you will notice if you build boost too soon with EGR off, not blocked, and not unplugged....you can log the EGR position...it will crack open because of the drive psi at low rpm's if you have too much boost. Just play with it some. Make small changes and you will see a difference.
