Hey Guys,
I put in my boost gauge on Sunday, it took longer than I thought it would, but that's just because I'm slow. I painted the pod, as I didn't want to hang a black one in. Turns out that DuPont's light graphite is a little too light, if you do this, try the medium stuff. (They didn't have a direct match for the interior code: L2.)
Also, I got some flexible vacuum hose, as the stuff that comes with the autometer gauge stinks. I used about an inch of it in the gauge, and cut it off at an angle, then stuffed the regular hose over it. (I used the nylon stuff as a nipple, basically.) Then I routed it to the place where the stock boost gauge fits in, and used a T fitting. (Easy stuff.)
The wiring I ran into the headlamp assembly instead of the fuse box. I tapped into the wires from the dimmer, black for ground, and light blue with red stripe for dimmer power. That way the gauge dims with the rest of the dash lights.
While I was there, I did the fog light mod, so now I can turn on my fog lights when just the parking lights are lit. Shibby.
Lastly, to make the boost gauge light match the dash lights, the green thingy that comes with it is a little too green. I took a blue sharpie and colored the bulb, then put the green thingy over it. Now it matches almost perfectly.
So now for the test... Vaccum works fine, and when I got out and onto it, I almost saw 11 PSI. This is with stock everything except for chip/exhaust/filter. I can only surmise a few things:
1. Chip allowing engine to rev further means more boost.
2. Adjusting the boost actuator is good for something.
3. The stock boost gauge is worthless. I never saw the boost there go above the 9ish range, while I've heard of other stock trucks burying their gauges.
Oh yeah, and now I'm certain I don't want more than a 2 PSI lower pulley.
If anyone has any questions, let me know...
