first turbo 2011 5.0

No. There we rumors that the new motor would not take ANY kind of FI, or handle nitrous well. That has already been dispelled by numerous cars making 500whp+ and running 10s/9s. I dont think that 6psi will be the limit as to how far it will go, but anything over 10 Im guessing either pump+meth/E85/or race gas will need to be used due to the compression.
