Interesting... my bung on my ERZ DP is drilled right on top of the bellmouth. Hopefully this isn't an issue for a wideband gauge setup.Divorsed wastegate wont stop you from getting a bung welded in. It should be welded into the downpipe midway down the drop section anyway. Putting it in the bellmought area is WAY to close to the turbo. Actually before you intall the pipe you should really have one welded in. pulling it again after to weld in a bung would suck. welding it in while its off the car is the way to go.
now go get yourself a walbro fuel pump installed and buy a stage 2 map.
