thanks for the spot check cpt. i think you might be onto something in regards to the sensor overcooling. however, i'm not sure how to verify that. I'm reading from two IAT sensors. The OEM unit in the stock location via the CTSC manifold and an open element via one of the side ports connected to my Zeitronix data logger. The OEM is much slower moving but they both tend to get to the same delta. I'll have to trust it for now I reckon.

My AFR readings are a bit more inconsistent at WOT which might be due to too much water or maybe a worn out O2 WB sensor. I did experience some bog yesterday and turned down the water flow. So you're right there also. I think i'll be happy with a 30F delta so I need to order a couple more smaller nozzles. After turning down the spray and still getting only a 25F delta the car ran great and the AFR was more consistent. If I was lazy I'd be ok with keeping it as is but i'd like to turn up the pump voltage to max but maximize atomization with a smaller nozzle.

Thanks again!
