Long story short. I blew up my 2.5, bought a 2.7 and am transferring all of the 2.5 electronics, manifold etc, onto the 2.7. So far its gone smoothly with the exception of an extra line on the 2.5 that the 2.7 doesn't have. I can't figure out where it used to connect on the 2.5 and can't seem to figure it out on the interwebs either. Does anyone know what this is? I'm hoping I don't have to take the 2.5 apart and move this part over. The last photo shows where it is missing on the 2.7
