Halltech Stinger "learning curve"?
Just installed tonight. Went for a few tests with the G-tech. Times are a couple tenths slower than with the modified air box. For those that have the stinger; is there a period of time the car must adjust to the air? Don't know what to expect as I have not used one before. Any input? Oh, if it matters car is an 04 coupe, MN6, Borla stingers and that is about it.

From the desk of Jim Hall:
"Allow 25 miles of driving to provide relearn time for the PCM> All fuel trims will eventually retrim to 14.7:1 except WOT. That will be leaner, but still well within the power range and will likely provide 5 to 6% more torque and horsepower throughout the rev band.
Please understand that new air will not cause your car to run lean. The factory air fuel ratio is 12.3:1 for Wide Open Throttle, which is way too fat for max power. Our intake does not need programming to operate properly, but will see added benefits from a good LS1 Edit program."

I found this on another C5 technical website, and performed the procedure with my Haltech Intake install. Later I had an LS1 Edit with dyno tune done, along with major transmission reprograming....
Here goes for the relearn....Sorry I didn't copy the URL so I apologise to the original author for not being able to give credit where due....
"Purpose
This page basically shows you step by step how to do an Idle Relearn. You would want to do this if you have done any intake modifications. If you do not do this, you may have hesitation or other issues.
Tools Required
None.
Do the Job
Follow these procedures EXACTLY or you will have to start from scratch.
1. Insert key into ignition and turn to the "On" position but, DO NOT START THE ENGINE.
2. Pop open the engine fuse block box cover and remove the two 10amp fuses from position numbers 16 & 23.
3. Your DIC will now display "check" messages for ABS, etc...
4. Turn ignition to the "Off" position.
5. Re-insert both 10amp fuses for positions 16 & 23.
6. Start your engine
7. Allow engine coolant temperature to reach a minimum of 176 degrees F and run at this minimum temperature for at least 5 minutes.
8. Shut down engine
9. Let rest for a minimum of 30 seconds.
10. Restart engine - check for DIC error codes (there should be none).
11. Drive car for a minimum of 30 miles at varying rpm settings and speeds. PCM will now re-learn and adjust for the new air flow and air temperature at the intake. "

Just did the same, took 4 driving cycles for it to show the SOTP feeling I was looking for. It felt soft the first time I took it out, but the last trip I could really tell the improvement...
Good Luck
Peace
