Tunning help with N2O

[XTREME80]

I have a 03 Xtreme 4.3 that iam playing with a 100 shot of N20. I am getting a little Spark Knock right after the 1/2 shift. I was wondering if someone could give me a little know lesson on how to tune a little better and recommendations.

Thanks.


(Noob in training) To HP tuners.
Wet NOS
No timing pulled yet (recommendations for best approach to retard timing)
93 pump gas
No wide band O2

not a nitrous tuning expert but when one gets here they will want to know if its wet or dry shot , what AFR you are running on spray , and are you pulling any timing from your tune when spraying ?

typically 2-3* pulled per 50 shot

Isn't the recommendation usually like 2 degrees for every 50hp?

Yeah i have been running 110 octane to avoid this till now. Im a bit of a noob to this and just got my tuner and would like to step down to some 93 or 100 octane. I would like some help step by step on the best way to go about taking timing out.


Thanks Shawn.

100 shot is tiny, pull 2-3 degrees and call it a day, 110 octane is not nessessary. 4.3s are not high compression

You can pull 3* from the entire table, select all, put a -3 in the box up top and hit the + sign. Or use excel

Or you can drive and see where you are under juice and select those sells and pull timing the same way.

Thanks fellas. Thats more or less how i was going to do it was 3* across the board.
