Pramtt - Thank you for posting the pic! Also the data was helpful as well. Seems like good evidence that the Andial IC does provide some benefit over the stock IC for that particular situation.
Lets keep this discussion on the Andial IC guys, oil temps have zero to do with IAT's. If it makes anyone feel any better my oil temps are just fine on the track regardless of ambient temp. I have two gigantic oil coolers in the front
CJ - Your correct in that the ecu will pull timing when things get too hot. When on track we are in a constant battle with heat. Higher Octane, more efficient turbos etc all help with temps but the IC must be addressed in order to help keep the ECU from pulling timing due to higher IAT's.
For the time being I'm going to start running my meth/water inj kit. On my other turbo cars my IAT's would go below delta on a normal run through the gears. Most of the time on track they would be around 10deg above delta most the time which isn't all that bad (this is with larger IC's though). Filling the tank every session can be a pain but its worth it imo.

I believe that higher octane only helps prevent detonation aka "knock" which is one of the parameters that will cause the ecu to pull back.
Very interesting chart Pram. Unfortunately I do not see two curves that are just differennt IC with all other parameters the same.

I'm waiting for my data logger to get here and will start this project in Oct.

Will do. I've used them in the past on my S4 with GREAT success. You can see in all the logs where under full throttle from 2k up to 7k the IAT drop below delta everytime. The meth also acts as an octane booster I'm waiting for my data logger to get here and will start this project in Oct.

Pram that chart is very good info. It would be really interesting to see testing with some other added variables - 100-104 octane fuel, colder spark plugs, cat bypass, water injection - on the IAT's. I have a scantool that reads IAT and can log it - I just need to figure out how to get the data to a computer

Eclou:
The data that I got was from the Maha dyno operator as both 993tts were tuned by Guenther for the UMW stage 2 turbos. AFAIK all those data was compiled from the OBD port except the boost pressure which was measured directly from the manifold.
The variation just coincidentally happened since there were two 993tt with different IC (stock and Andial), different cats (stock and 100cells).
The data I got from the dyno operator was in pdf file that later on I inputed manually to my MS Excel file in order to plot out the chart.
