d-1sc my friend has an 01 SS m6 with procharger, and was looking at going from the ls6 intake manifold to the FAST 90/90 setup, is it worth it, any additional mods needed?

I have been told that you will not see any noticable gains on the dyno by going with the 90mm TB and intake with that setup.

I would recommend using the 78mm. If you were planning on spinning the motor above the normal power range I would recommend the 90mm. useing the 90mm part you would notice a lack of bottom end power but a very raucous high end power gain.
even if you have the procharger installed you would benefit from the 78mm setup.

Not on a blown application and based on other results unless you are reving past 6500RPM.
With my setup there was no gain. I rev to 6000. I went from the LS6 and stock TB to the 90TB and LSX.
