boost gauge
i have a friend with a 96' PSD and when he accelerates once his boost gauge gets above 15 psi it starts to get shakey, but it still will keep climbing. i guess my question here is why would it do this? any help yall have would be appreciated.
thanks, Austin

Several things could be causing this, location of boost feed line tap, low quality gauge, small leak in the boost feed line, leak in the post turbo boost system (around boots). Truck shaking so bad that everything bounces (just kidding).

its my truck but my computer wont let me start threads for some reason. (thanks austin) the gauge is an autometer and the splice into the line is about 3 inches from where the barb is for the computer i already replaced all the fittings and it seemed to improve a little bit but i hadnt thought about the boots leading into the intake runners. any ideas on how to check and/or fix this???

one boot to check is the orange one between the air box and turbo, the only orange one I suppose, its mounted on the air inlet of the turbo. These are nitorious for splitting on the bottom where its clamped, one thought could be that it might be broken so bad that its "vibrating" as the air is rushing in under high boost causing this flutter in the boost.
I dont know, its a long shoot and now that I've typed it it sounds like bullshiat. Check anyways, you dont want to be pulling in dirt

My 95 does the same thing, its not the gauge, I had the same gauge in my turbo beetle and it worked perfect but only went to 12 lb of boost, then I put in the ford, check the orange boots, all good and replaced the rubber o-ring to the turbo?

I'm not a machanic but I assume you could put an air gun to the line that the boost gauge is on and fell for a leak at the boots?

any one have an idea on where i could get a hold of a set of boots on the cheap. all three of them including the one right before the turbo, and the two that are going directly into the runners
