NO RIGHT NOW IM RUNNING HIGH OCTANE FUEL ACTUALLY....LIKE 103 WITH THE ADDITIVE. COULD THAT BE PART OF THE PROB??

Yeah that's a little extreme....I'd stick with 93 octane or 91

Why are you running 103 octane...or are you running 93 and fell for some gimmick "octane booster" and you think you're running 103 octane?  If your motor's stock 89 will do just fine.  The higher the octane, the harder it is to ignite and the slower it burns.  Maybe that has something to do with it.  I don't know....but what exactly went "BOOOM"?  Can you give a better description of exactly what happened?

How fast did you get going? If it was over 100, you likely just hit the speed governor. That's s'posed to happen (according to Nissan, oh well, it makes insurance cheaper).
