Throttle body issues p2101
Its a s/c 14 z51 and its basically flat lining on the data log when,i floor it...From a dead stop hook on sticky tires soon as the boost kicks in the car goes flat and after few sec it starts slowly pick back up speed after i release gas pedal and press it again ..throttle seems to shut causing no boost are anything..car has headers ,procharger..what could possibly be the prob???

This is what's happening... The airflow model does not match the throttle percent for the given load... So the computer sees this is a problem and shuts down the car via REP.....
Simple fix... Go into engine diag and raise the threshold...
Your "tuner" should know this...

Well that makes sense...

I agree with TA, Engine Diag is the first place I would go, there are several tables in there that need to be changed.
Once that is done, the torque model itself may have been changed improperly.
