Nitrous Oxide - do I have too much timing on the spray??

I just put on back the 150 shot after my heads/cam install.

I did see 26,5 timing on the 100shot, but
on the 150 shot I see up to 30,5!!!!!

Is that a problem??
What can I damage when leaving that like it is??

I do run the setup rich (0.96) and see O KR.

Do I need to retard the timing myself, and if yes, how do I do that??

BTW, I had the 100 shot runninge leaner ( 0.89) and then richened up with the MAFT for the 150 shot (0.96). So ca that be the reason to see more
Timing. Can that be because I run richer on the 150 shot??

Thanks,
Michael

Well...if your seeing 0 KR then atleast there is no detonation present (provided the system is working). Wether or not that is the best timing for power on the juice is hard to say....youd have to go to a dyno or a track to test it out. You can retard timing a degree or two by installing a 200 ohm resistor into the IAT plug. Or a 0-6k potentiometer and then you can read the airtemp sensor reading on Atap or scanmaster and adjust the temp as necessary with the potentiometer. Maybe 150 deg F or so. Youll have to experiment with it a little.
