I installed a 90mm throttle body on my LS6 intake lastnight and now it hisses really loud at idle and damn near dies when i come to a stop. It seems to idle really low. Is this normal?? Do i have to do anything different with the map sensor? diagnostic said low Manifold Absolute Pressure. when i reset the code it went away but still idles really low and hissing continues... Any suggestions or experience with this issue?

Drill a small hole in the blade or the easier way i did adjust the blade to be opened a little till it idles at about 1k-1500 RPM

Hope this works for you.
