Who has tested there turbo back pressure?

Folks, keep in mind that the cold-side is just as influential on backpressure as the hot side. Restrictive piping, restrictive intercooler, small TB, small compressor, or even a small air filter will a) reduce boost in the intake plenum and b) make the turbine work extra hard to spin the compressor in an effort to reach wastegate setpoint. Both of these make the E/I ratio worse.

Very true....also the fuel used. Meth and Alky will have a definite effect on backpressure reading as well.
