I was on phone every day with Blake, at first nothing made sense. Once I decided problem had to be with IAT read out, I suggested the IAT table in Tune was off, I have seen this with EForce, they use a TMAP that uses Ford IAT table in Tune. We had a tuner accidentally drop the GM table in and IAT temps were crazy.

After Blake verified tune was good I said it had to be wiring or a bad IAT sensor. No way does water temp go down 50deg and IAT go up 10deg. Blake is hitting it hard with big engine, 17lb boost and Whipple has a very good Intercooler so he wont see the 30-40 deg water most do. Once he dials in Freon charge it should be good. IMHO higher water temp in this case is a result of taking a lot of heat out of the blower. Even at his initial Freon charge he was seeing the guaranteed 50 deg reduction in ICWT. There are advanced adjustments we can make for a high heat application in house but it’s difficult to relate this to a first time installer.
Thanks for hanging in there Blake and good work!
