I think I might have misspoke. I am used to S550s since iat becomes iat2 with the maf breakout harness. I am going to make an update on the lower and temps after we dyno the car. I am seeing very different activity with iat2 temps. Rapid rising and falling. It makes sense without the bypass area but I want to do some more testing before saying something for sure.Andrew, I am curious to see some data on that IC core. You made mention that IAT's were nice and cool at 77* so the core was working great, but you were looking at IAT1.
Can you advise how IAT2 is looking as that shows effectiveness of the core.
