when im driving around i have no boost reading. the only time i can see my gauge move is at wot. i have a manual boost gauge with the hose hooked on the y thing that goes into the turbo is that a bad spot?
Unless your really easy on the throttle or just cruising you should at least see 1 or 2 psi. The more you get on the throttle, the more boost you'll see. If it only moves at WOT then there might be a problem somewhere with the truck, or gauge. Also, what does it get up to at WOT?
I wonder if you might have a kink in the line or perhaps a fitting that could be leaking. Also, the range of the gauge you have will have alot to do with what you see. If you have a, say, 60 psi gauge, then it would not appear to move off of zero under normal steady-state driving.
What is the max number on your dial and what is the max reading you have been able to get the needle to read? My stock turbo winds out my 30psi gauge. How 'bout yours?
I'm having a similar issue with my truck... 30psi Isspro gauge, and it only shows boost when really into it and the gauge makes a buzzing sound. No kinks in the tubing. Fittings tight and teflon taped. I've heard the restrictor orifice in the gauge can come loose sometimes, I just need to tear my pillar pod apart again and check it.
My last truck had a 35psi Autometer boost gauge with a Garrett ball bearing turbo. The highest I got it was 33psi at WOT in a race, under normal driving conditions I'd see 15-20 around town and i'd let it sit at 5-10 cruising down the highway. This is in a 5 speed manual though.
