Nitrous Oxide - 150 shot with sunoco 104 octane how much timing?

Hey guys im going to be sqeezing a 150 shot through the car here in the next couple of days. I usually squeeze a 100 shout and i pull bout 2 degree with the sunoco 104 just to be safe. my question is do you think that i could leave it at 2 degree with that much octane. i have had pcm for less tune the car but not for n20. So I think that they advanced the timing 2 degrees. my mods are listed below

For a 150 shot I would start by pulling 4-5* of timing

so I should pull 6 degrees since it was advanced 2 degrees by pcm forless?

no...4-5* from your NA timing.

cool thatnks for the help!! by the way i am running your lt1 plate setup and i love the way it works.

I would get a acurate reading of your A/F before you spray. are you mixing the 104, stand alone, or just straight 104?

i would say 80 % 104 with 20% 91

With that gas...0-3 degrees probably.

26 degrees would be what i would do.

find out what your timing is at N/A and pull timing accordingly. you may need 5-6 degrees or 3-4 depending on what your timing is right now.

yea whats timing n/a and then whats timing on the 100 shot

well if you are going 100 hp now and 2 degree of timing out.. then go 3 degrees is ok. rule of thumb is 1 degree for every 50 hp

i'd leave it where it is (-2*) with the racegas.

I run 22 degrees on 150 shot

Pull the standard 6* back for the safety part of it and creep up. With the race gas in it you may get back to -2* or -3*. Watch your knock retard under load and adjust. Fine tune the fuel to get your AFR readings after the timing has been set. Then go back to check your timing and make sure your safe under load. Good Luck.
