Ugly KR on 100 wet shot!

[v8s10s]

I thought I had it tuned descent from what I've learned on the forum . But I guess I need to learn a little more about the funny stuff. Without the spray I've never had KR . The first time and only time so far spraying is showing up to 14* KR . The wideband shows 10-10.5 afr. on the spray and 12.5 to 13 on the motor . I did'nt think 100 shot would could screw everything up that much . I've got TR-6's gapped at 35. Plugs look rich as the wideband says. I would like to get a few opinions on the matter . Thanks.

Also, It made 383hp/356tq last week (seemed a little low). I was hoping for a few suggestions about getting a little more. Iron lq4,l92/l76 combo, 226/232 113 cam.

what is your timing at?

[v8s10s]

29* but if I drop it 4* it loses a good bit of power on the motor. I tried that before I sprayed it and it lost a good deal of power .I only tried it once at 29 and did'nt hear any detonation at all But apparently there was 14 degrees of it. Maybe I have something wrong elsewhere in the tune.

29* of timing on an LS motor with a 100hp shot of nos is probably the cause of your detonation

Tried it with 24* and it has the problem. Would too much fuel cause the KR ?

You need a wideband to see what AFR your at. Reduced timing for NOS seems to always have been a requirement, even on carb'd motors.

I have a wideband. 12.5-13 on the motor . 10-10.5 spraying.
