I just got my 2003 platinum silver WRX 2 days ago with 16 miles on it. I am already aching to do some mods, but first im doing my homework on the car.
First, I wanted to install a boost gauge. My question is where is the best place to tap your boost line into? Some people tap into the fuel pressure regulator hose, while others tap into the hose connecting to the factory BOV, right under the intercooler.
The BOV hose seems more correct to me, besides what does fuel pressure have to do with boost? Does the fuel pressure regulator depend on boost to operate? I would appreciate any feedback.
