Conan from what i've learned big cams need lots of airflow at low idle, You might try lowering airflow table in idle areas to help, this will cause the TB to open more to allow more airflow, also timing can cause this as well but not as much. How much have you changed your idle spark error? This error controls the amount of spark adjustment vs rpm error at idle in P/N. Adjustments here will have more effect on idle sound as it will let the spark swing more or less vs rpm error. Talk to tbrtuning he has spent many hours on these cars and really knows his stuff, he even has a killer tune for the hp70 trans that helps it last under big power and his prices are good not to mention his killer customer service. That's who did most all my tune, He helped my understand how and what works rather than just writing a tune. To me that's worth more..
