Following the lift at the traps, the iats will continue to climb but only for a second or two and then the iat immediately starts dropping again as seen in the logs.
All my logging has been on the street immediately after driving around. I drive down the highway 2 miles, quickly slow down to about 15 mph, then roll it to the floor and hold it there till about 125 mph.


I also am running 12psi with only 1 Vortech race bypass. I ordered another one and a flange today. Ted suggested running 2 of them over 8 psi. Might help some with the heat soak from high IAT decel. Ill also try a run starting without a drive around and hard decel first.

I don't think want meth as I already spray a 100 shot wet. That cools the IAT I'm sure, but I want them to be pretty low off the spray.
