Hey I was just wondering for those of you rupnning 75-150 shots what kind of total ignition timing are you running? I was looking into putting a 100 shot on my 2002 Z28 but I have tried to play with my total advance for more power on motor....so just seeing if I should return it to stock setting if I spray. Thanks in advance.

If you have advanced it any from stock I would either pull a few degrees (1 or 2 per 50 hp added via the N2O) or run a higher-octane fuel when you spray. If you want to run the advanced timing map NA and only pull it when you spray take a look at the LS1 Timing Tuner. Here's a Link for more info.

Stock timing here on a 100 shot. You should be OK on stock timing up to 150 shot, then you need to start pulling timing

It depends on a few things.
First do you plan a 100 dry or wet shot?
Second is how you advanced your timing.

If you only advanced in only the load area of your timing table where you hit NA WOT, then you can use the area below this (more load) for your timing retard while on the bottle if using a dry system. The higher MAF reading increases the load/RPM and uses timing value from those other cells.

If running wet, then you'll either need to reflash before spraying, or use one of those timing retard devices.
