Default Hesitation @ wot with a standalone and nano setup

I've dropped my window switch from 3800 to 3400, purged the crap out of it, but still getting hesitation at wot. It comes on like a bat out of hell around the 60' mark.

No fpss and running a 6an w/filter for the main line. My nitrous line from the noid to the plate is a foot longer than the fuel line. I logged the run with my wideband. At wot, it started off in the 13s a/f, with a brief 17:1 (lean spike?), then it dropped down into the low 12s, high 11s a/f from there.

Any ideas? Could I still get a lean spike even with a standalone?

Yes you can still get a lean spike with the stand alone. And it sounds like you are.

What jetting are you running? How much timing? What FP?

I'm running a 78N 33F jet, 14* of total timing, #9 plug, 110 leaded in the standalone set at 60 psi. Bottle and nano was full also.

I didn't have this problem before the new setup. It came right on when pulling fuel from the rails with the racetronix.

Unless the wideband is off and/or the sensor is going bad. The other sensor is already dead.

maybe turn the fuel pressure up in the standalone?
