Got my isspro gauges finished last night...I love them! Took it for a test drive when done, and then romped on her up a pretty good grade. At WOT I saw 20-21lbs. of boost, 900 on the egt (I forget what the increments are on the egt gauge, I'll have to double check, it coulda been a little higher), and my fuel pressure with the FASS 150gph system was 21.5psi at idle, and never dropped below 20psi at WOT. I feel so much better knowing what my truck is doing On the down side, the plastic ring with the terminals in it on the back of my A-pillar speaker broke off when I went to reinstall it, so I gotta get a new one of those, and now my left outer clearance light doesn't work for some reason. I know its not getting power to it (checked with the volt meter last night), but my wiring from the wire tap all the way up the a pillar is ok, and all the other lights work, so it must be that lights wiring under the head liner (weeee).
