A turbo will not the hemi if properly tuned, period.

And I have to say that I seriously doubt that claim of 500hp with those mods.

Many hemi's that have the turbo use the smt-6 hemi tuner kit and they work fine. My 04 doesn't like the tuner. There is some sort of conflict between the smt-6 and my 04 pcm.

Hopefully, hemifever will come on here and share some info. He is the #1 tuner of these kits that I know of.
