Boost and torque gauge not working correctly

[87 Buick GN]

The boost almost never shows anything. Torque is all over the board. I did vent my stock bov, not sure if that has anything to do with it(I’m doubting it). Any hints to fix this before I go to the dealership

Welcome to the group. It has been posted before. The gauges are not accurate at showing you what is going on with the engine. Someone else may chime in with what they use to see these.

They are not gauges, in the sense of actually measuring anything. They are just the computer throwing out some numbers based on throttle position, engine speed, etc.

I don’t believe there is an accurate way to even measure torque without being on a dyno and even that is somewhat of a guess. The torque gauge is more of a gimmick.

Have you watched it in sport mode while accelerating hard? Under most normal driving conditions there is little to no boost.

My torque and boost "gauges" move logically to what the engine is doing. But really, they're just toys to me. I don't "use" them for anything.

Do you "feel" boost at WOT? Any lower performance?

That, would bug me. I want my "toys" to work as intended.

Yes it has boost. I can hear the turbos and the bov

Was it working before you installed a BOV?

I only vented to atmosphere the stockers

I wonder if you may have a vacuum line disconnected or hooked up incorrectly. The line that boost is read off of.

Just trying to help. If he has anything aftermarket done they will likely try to pin it on him or the parts. The majority of dealers as I am sure you know, suck.

Agreed. They suck and possibly a waste of time. Besides a re-flash I doubt they can do much.

Coming from a GN, you should be used to the stock boost gauge not working

True but that kinda works. I don’t use it at all but the stinger has a problem with it
