So I just bought an 2006 ltz and it runs less than expected up to 3/4 and then it bogs like crazy from then to full throttle, I opened up the carb and unblocked a jet I think it was the pilot jet but there's still no difference? Help?

 

Did you buy it locally (need a different main jet)? Is your air filter super dirty and clogged? May want to clean the entire carb, not just one jet.
