"Typically" you remove 2 degrees of timing for every 50hp of nitrous. Race gas you can probably be less conservative.
"Typically" catheral port heads like 25-27 degrees of timing

Without a dyno or at the track, it's hard to know how much timing is enough and what is too much.

Regardless, reading spark plugs is the only way to know for sure.

Its actually already tuned my tuner wanted a spark plug reading to see how buch more timing he could add. just that i sent him the pictures but he hasnt got back to me yet. i would up the timing my self but im not sure on what table he lowered it on both spark tables show 28 degress but data log shows 26 at wot my tuner lives in another state

There are several tables that will add/subtract timing from the base spark table. IAT being the most common.

Looks like i see how he took the timing out looks like he used the fuel table in spark its called afr spark advance correction
