Supercharger boost gauge
I often see supercharger gauge needle going back and forth a little at idle, and sometimes at constant speed on my 18 ZL1. Is it supposed to be going this? I am assuming it should be constant at idle or on same speed.
Correct me if I am wrong. Thanks! |

Your boost gauge is perfectly normal! I know you think something is wrong but it’s operating like it should. I know I thought something was up with mine too after I got my Z back in March but it was okay!

A little fluctuation back and forth is fine. These are not super expensive gauges so you gotta expect a bit of fluctuation.

Personally, this gauge has always bothered me. I mean, how can a blower be reading negative? Is it pushing air back through the throttle body? I don't see how that is even possible...

Cheap gauges and reading vacuum???? What the hell is wrong with the answers...…
Yes, it will fluctuate a touch at idle, cruising and under boost. Just how it is |
