Question on timing for 100 shot. I have a dry nitrous system installed in my car. I got my car tuned before the nitrous, I have an ms3 cam and 243 heads. Not sure what timing is right now... I have venom computer controlled system, even though its computer controlled I don't think it will adjust timing. Suggestions on what to do please. I was going to buy a diablo handheld tuner and adjust timing myself but I wouldn't know how much to retard it from where it is now. Is there a certain point I need timing to be for 50-100 shot?

Your best bet is to do some searching, there is a lot of great info to be found.
Rule of thumb is to pull 2 degrees per 50 hp of nitrous.
An easy way to pull timing is with an IAT resistor mod, do a search for it.

I am pretty sure WOT stock timing is 28' (99's are, for some reason I think 02's ran less from reading????) but you are tuned so it could be more plus your cam could have advance ground into it so you will have to do some investigating.
I seem to recall that the resistor mod pulls 3'. On a 100 shot that would likely be sufficient but reading AFR's and more importantly, your plugs, is the best way to judge.
IMO, you should look at investing in HPT of LS1edit. Log NA WOT runs to see where your timing is at then pull out anything above 28 plus the 4 and go from there with your timing and fuel.
Trust me when I say to search and read. This site has a wealth of info to be had. I spent countless hours reading and rereading before I ever opened my first bottle.
Good luck, you will love the nitrous.

You would pull timing from where you are now with the cam. if you spray 100 you should pull out around 4 and then go from there. If you spray 50, pull 2 degree as a starting point.
