After lots of research (John reads a lot websites to learn stuff) he decided on a engine control system from Banks Engineering. http://www.bankspower.com/ Choosing the Banks Economind and IQ monitor I have increased engine power, control and monitoring all at my drivers fingertips.

In addition to the Banks IQ system John installed a Banks Cold Air Intake and a Super Scoop in order to move the air intake from inside my engine bay to outside the engine bay and lower. This allows for cooler, denser air to enter my turbocharger thus keeping engine temps lower. The IQ system reports an 80 degree difference between engine bay air temp and outside air temp which again helps prevent over-heating problems.
The last modification John wanted to complete on my engine to make sure I'm running at top power yet not creeping towards over-heating was changing out my turbo mouthpiece. This is a acknowledged design error on the part of GM when they switched from the LB7 to the LLY engine. This mouthpiece is too small and restrictive thus another possible cause for over-heating. So he ordered a larger cleaner flowing mouthpiece fro AFE and installed at the same time as the Banks CAI. He also removed the plastic resinator and the rerouted the pcv system so that oil vapor is not routed into the turbo.Thus keeping the vanes and inner workings clean and oil free.
So far according to the notes John has made during each of these changes there has been a small gain in MPG (1-2 at most) but my engine is definently running cooler and there is no sign of over-heating or the thermal run away.
The cooling fan does still run when needed but not as often and for shorter durations. My large Texas bumper may be causing lower airflow issues so a chin deflector or air dam may need to be fabricated but that is another days project.
