Ok- the important numbers there are the rise from the start of the boosted run (34c?) to the 36c at the end. That looks like a good intercooler setup to me. And I agree with Chad- that grill is probably blocking more air flow than you think.

I'll try removing the grill after work today. Then I'll take another run up the hill. I put the grill in because I was getting tired of my intercooler getting banged up. Oh well.
I'm away for the next week so if I can't get it done this evening it won't happen for at least a week.
I also think I could improve the airflow if I put some ducting in to prevent air from flowing below my intercooler and out underneath my underbelly pan.

Here's more logs with the Moss high-flow grill removed. Both were done in the same locations as my other logs above.
The delta is with respect to the previous "upcut" log.
Beginning:
coolant = 27C
AIT = 20C
Same coolant start point as previous log:
coolant = 45C
AIT = 23C (delta = -1C)
At highway on-ramp (drove really easy):
coolant = 95C (delta = 0C)
AIT = 20C (delta = -14C)
Base of hill (some significant boost events getting there):
coolant = 95C (delta = 0C)
AIT = 29C (delta = -5C)
After longish boost up hill (couldn't get into it as hard as last time):
coolant = 100C (delta = 0C)
AIT = 31C (delta = -5C)
I was much more aggressive driving down the hill this time and my coolant only went down to 92C but my AIT still went down to 28C.
On a related note the daily max temp for the first log was 3.5C warmer than it was today.
Even taking into account the difference in daily max temp it looks like removing the grill has definitely had a positive impact.

well **** check this out:
Looks good dont it? Normal. ambient is low 80s today. that was just in neutral in the garage.
see I had the hydra harness still intact using the factory sensor in parallel with the GM sensor. Oops. Cut one wire and it works fine.

Rob, you'll be happy to know my car is healthy again.
Ambient temps were low 70's F and 70% humidity. this followed a half hour drive. minor traction issues in 1st...
