blitz s/c power off-boost?

[thebarber]

has anyone contemplated the difference in the off-boost power on the blitz?

i only ask as i have a friend who just put a tte supercharger (made by blitz) from a corolla tsport onto his matrix xrs and before he got the belt/pulley stuff worked out, he threw the intake manifold on. he said lift was useless and the power was weaker than w/ the proper oem intake manifold

just wondering if anyone w/ a blitz supercharger notices much, if any, difference in power when the supercharger is in the OFF position? or if anyone who dyno'd their blitz'd yaris ran one w/o the s/c "ON", and perhaps when the car still had the "stock" intake manifold...
