Any one know how to back of timing for nitrous use?

I know with nitrous you have to back off the timing and use 93 octane
I do not know how to do this with out a programer on these new stangs

Have a Granatelli fuego. Tech support says they cant comment on
how much timing is added with there tunes. Ask about using nitros
they cant comment on that WTF. With the Fuego i guess im on my
own.

May have to send programmer back , also fuego does not do data logging
like grannatelli says. When you ask tech support about data logging they
tell you it wont do that yet, but is comming . They wont tell you when 2wk's, 2mo's,2yr's

You really need a tune that is specifically set up for nitrous and locks timing down so it won't change.

For example, you could adjust timing on the handheld, but the knock sensor could add it right back in, thats why you need a tune just for nitrous.
