odd one here; I have an after market auto master sport comp boost gauge, at idle when my heater or AC is on my boost gauge pulsates between -15-20 I've checked all of my piping and done a boost leak test and nothing , something I should be concerned about or no?

Does the rpm surge or stay stable

It's in your tune. I'm going to assume the rpm doesn't change enough to notice on the tack, but through hptuners or with a aeroforce you'll see the rpms vary from 750-850.

Contact your tuner and get them to fix you high load idle.

Can u hear a difference in the motor? I had a mad maf that did that, if motor doesn't sound diff it's probaby a bad gauge
