Is your motor built and 11.1 CR ???
I notice that the power/torque starts to fall off at 5000 RPM.

Is this the AAM kit ???
They use the EFR6758 but with the 0.64 housings in their kit...
These housings offer a more snappy response in the low/medium end [less turbo lag] but power drops off up top.
The 6758's are also available with 0.80 AR and 0.85 AR housings that give you more power at the top [better for racing] but you do get more turbo lag.

Mine's down there for the TT install and this is something I need to seriously consider at this point.
Thanks,
