Help me out
I just installed a BBK 80mm TB and my idle is higher, also when I let off the brake the truck wants to move on its own up to 35mph, goes through gears itself to. I do have a KBB supercharger attach with KBB tune. Should I get another tune or did I do something wrong. This is on a 2003 silverado.

BBK throttle bodies have been known to leak.... did you over tighten the throttle body??
if you overtightened it... it might not be able to fully close.... take off the inlet tube, and see if it closes all the way
