    Does anyone know how to retard the timing on the 6.4L SRT8's?? I want to run 100 shot of nitrous oxide. The nitrous oxide dealers recommend retard the timing 4 degrees but I cant find anywhere online on how to do it or if it can be done at all. Help!!

    I agree.. a blower/supercharger or even a turbo would be awesome!! BUT they don't make it for 6.4L YET. That is something Dodge might have made a huge mistake in doing. That is locking or making their system uncrackable in the 6.4L when mods are coming out for mustangs way before the model mustang even hits the market. Now people who want or have Challengers are limited in aftermarket upgrades due to this issue of the computer not being unable to tune.

    You don't need to touch the timing with a 100 shot you may want to run a colder plug but you don't need it until you get to a 150 shot.
