Check for exhaust leaks at your header. Check for leaks at the evap solenoid under the intake manifold (straight under it, directly in line with the a/compressor)
Check all your intercooler piping. Also, datalog and post the logs here using datazap. Your tuner cannot help you if he's remote; find someone in person who can help resolve them. It's likely the car has no throttle response because it's yanking timing due to your fuel trims
