04 Mustang Nitrous Tune

[Stangboy04]

I have a 2004 Mustang V6 and im running the 93oct tune on my U7146. I've just installed a nitrous system and I know I need to change the timing for nitrous because the tune advances timing and I need to retard it. Im running a 75shot most of the time and 100shot max here and there. How can I use the 93 tune with nitrous? What should the timing % be changed too? Thanks

Rule of thumb is -2 degrees for every 50hp.

So if im running a 75shot could I get aways with just -2 degrees also what would that be % wise on the tunner? Would that hurt if I ran -2 all the time since its my daily driver?
