Assuming the Phantom is reasonbly accurate the stock one on mine isn't even close. The stock pegs @ 10+ PSI while the Phantom reads 8 PSI.

I have the Phantom also. My stock gauge is very close to what the Phantom reads, within a half.

 

stock reads an 8 while the Autometer guage reads a 9.5-10...never seen the stock guage peg.

 

I don't have an aftermarket gauge, but my stock gauge on my stock truck pegs the gauge,and I know that ain't right. Does anybody make a pillar post for the lighting or do you have to modify a mustang one?

Have any of you compared how the stock gauge compares with the aftermarket boost gauge on accuracy?

 

Thanks TampaBayLightning, and a big thank you to Brian K for a detailed post.

 

My pleasure.

Good luck
