If you use the din filler, I'd be nervous to look off the road when boosting. Glove box you can't see it, and piller looks very non oem (for those who care).. But above the ac control Like here looks very oem, It's close to the tachometer (which would be important for me) and you can still see road at same time. When I get a turbo this spring, this is definatly the one i'd want to put my boost gage in. The other locations are ok imho for other things that you are not going to look at with your foot to the floor. It looks much better then the Border one IMHO too.
