Hi guys, I'm the one tuning this truck. The IAT table is set up to run the commanded timing until 85C then it retards the timing 2* and at 90C it retards 5*. The IAT's cruising around when its 78F out are in the mid 120s and and quickly get into the 180s only doing 0-70mph wot pulls. So up until around 70mph its running at 19* of timing and then tapers down after it hits 185F. I started tuning it with 10* of timing max and we worked our way up to 21*. It still made decent power at 21* but seemed to run better at a safer 19*. The KR sensors have never went off in this truck doing wot runs and it makes noticeably more power at 19* then it does at 15*. Its running at 11.5afr on the WBO2.
I 100% agree that 19*of timing is allot to run on just 92 with IAT's that high even if its only 5.5 psi. I explained this all to him and he wants it left there for now.

 

Good luck with that. No way I would set the timing that high with a IAT modifier set to not pull till 185*
