i did the forscan mod and i now have my boost gauge on the dash but i notice it doesn't tell me exactly how much boost. i get the temp gauges working fine. is that normal?

Thanks!

 

In previous yeas, boost gauge was never a forscan thing.

I don't recall if numbers appear on the boost gauge (I don't have my truck anymore).

I can't imagine 2021 made the boost gauge on/off a "FORScan only" modification.

 

im referring to enable the psi amount with forscan.

 

What engine do you have? I have a 22 5.0 with Whipple plans and am just wondering if the boost gauge will even work and if I have to add a sensor and pin into the wiring harness, or if it's just a waste of time trying.

 

Psi won’t show below the gauge.

 

The boost gauge has always been there and NO you cannot put the PSI numbers to it----I wish we could!!

 

The numbers would be nice, but not really needed. The gauge range says 0-20, so you can approximate fairly accurately. I've seen mine go above half (10 psi) maybe once or twice ever.
