I bought this for a 2005 GTO. Yes, my car is a DBW and originally had a Silver Blade style throttle body. I installed this and it works great. Confirmed with Tech 2 that the TPS readings are correct. I've had this on my machine for almost three weeks now and have done several WOT runs and there have been no codes and no messages of "Reduced Engine Performance" or anything like that. If you have a 05-06 GTO and are in need of a throttle body replacement this is worth a try. Here is a thread I created on the LS1 GTO that explains my findings.
