I wouldnt say yes in regards to the butt dyno. But it will help sppol quicker, also depending on cam, etc. It will give you an increase via effiancy. If your going turbo.. i see no reason not to. You should.

Whats your goal? To me, if your building a head.. u should. If your just running low boost and not going to push the setup, then its not really something id spend money on.

With the low comp 8.0:1 iirc the srt pistons are.. id say do it. Your turbo will be working hard. The os will make it more efficient at its job. Also upgrade the valve train for you cam u plan to use

you can always trust a dishonest man to be dishonest, honestly, its the honest ones you need to look out for. you never know when they will do something..stupid
