will an aftermarket intake lean me out the PP typhoon intake and throttle body had been ordered(85/85) . my car has been dyno tune...will it lean out when I put on this better flowing setup.
Yes although going from an LS6 to this setup isn't a drastic change in airflow you will still benefit from retuning to take advantage of the increased airflow. When I put on my FAST 90/90 I was definitely leaner than before especially in the cells above 5K rpms.
your idle may go up a bit, as you have more air flow. I would throw it on the dyno to see what the A/F is. I would probably get a retune- talk to your tuner and work something out- you don't need a full tune.
