Alright, I got the wrong TB. I just got my Vortex Ram Air. I know I got too much air going with the 58mm already. Option 1=keep the 58mm for now with no Ram Air. 2=put the 48mm back on and put the Ram Air on. 3=Put the Ram Air on with the 58mm. 4=Put the 48mm back on no Ram Air. I will get a 52mm to replace the 58mm, but it is going to have to wait a couple of weeks, if not longer. Anyone want to trade.
