Need a check on my Nitrous Barracuda setup

Hey guys been reading up on Nitrous applications on the forum and internet, I believe I have got a good setup and was hoping some of you more experienced guys could give me a peer check and make sure I'm not missing something. I'm wondering if it would be "safe" to run a 150 shot on 93 octane pump gas with my setup?
