Hi all. I just got done installing an HKS boost gauge in my '02 WRX. I used the J-spec tuning instructions as to how to do it, and they worked out well. I got the electrical part hooked up fine (dims when I use the dimmer, etc.). The vacuum hose part is hooked up fine as far as I know, but I think I have a problem with the 3-way connector that I bought. I bought it at Autozone, and it does not have the brass pill in it which I think it should have. In the instructions it says that the gauge will work without it, but will be erratic. Well... that seems to be the case. My gauge is measured in kg/cm.. which is just about equal to Bar. I should be getting almost to 1 bar at full boost in 3rd~ gear or whatever (whenever the car hits 14~ psi.) My problem is, when I start the car... instead of having the needle sit at 0, it sits below... at about 500 (mmHg I believe). In first gear it goes from 500 up to 0 (never above), in 2nd gear it goes to 0.5, and in third it goes to 0.5 (haven't had the chance to test out 4th or 5th - only took it up and down my street.) The car feels normal, no drivability issues or loss of power... so I'm pretty sure it's just the gauge/T-connector acting funky. What do you guys think? Where can I get one of the T-connectors with the brass pill? I got the only ones Autozone had, and I'm not sure where to get others (maybe Lowe's, etc.?) Thanks for the input and advice... any and all are welcome. Here is a pic of the gauge installed (matches the stock gauges pretty damn nicely)... Enjoy!
