NGK would definetly have 2 steps colder.  search on their website.  the number  in their spark plug code represents the temp. the lower the number the lower the temp....
Working on obtainting an M-Class license... ?? Hint: 2 wheels. 
 
For your information : TR75IX are the two steps colder, with NGK, the lower number the hotter temperature, the higher number the lower temperature, I just bought 6 today.
 
has anyone ever had a problem with motorcraft plugs?
 
so im thinking i only need a 1 step colder plug with 7-8 psi from the mp45 charger and a 55 shot of nitrous????
