Default NW102 issue

Anyone good with HP tuners or have had this issue?

I have a 09 Z06, heads, cam and installed a MSD intake with NW 102. Car was just tuned with no issues. Anytime I do any full throttle pulls and come to a stop I have no throttle. Almost like it puts the car in limp mode but no codes. I can push the gas pedal and little to nothing happens on the tach. I have to keep pushing the gas pedal just so it would reach maybe 2k rpm so the car could start rolling. Once the car gets moving it suddenly comes out of like a limp (comes to life) and then drives fine until the next stop. If I drive the car normal and never do anything full throttle I have no issues. It’s only after I do say highway pulls or full throttle action. I have my tune file and data logs of of this happening.

Do your logs show the throttle plate opening as you press the pedal?

You may need to add a couple grams of airflow to the minimal idle air flow tables. try 2-3 grams
