I want to install one, but is it simple, or will it take all day? I've been reading about boost spikes with exhaust systems, so I figure I should get one before I do my exhaust.

The factory one is hooked up to the vacuum line that goes to the top of the BOV/ Recirc. Valve. They just put a little "T" fitting onto it & run the hose to the gauge. Pretty simple if you ask me! Hope this helps.

Will.

Depends on how complicated you make everything. I'm a wiring nut, so I had to make a nice harness for my three gauges with 2-pin plugs, shrink wrap etc, and "had" to have the lighting dim with the dash lights. Also, when it came to boost, I also put in an adapter off the boost line for a Hobbs switch (for my IC sprayer), and I also ran everything in -3 AN, so it took awhile to route everything, plus I ordered everything in advance. For the "normal" installation, give yourself 2 hours or so.
