Inaccurate readings on BOOST from Commander
 

Most of the readings for the PFC are right on. Only complain I have right now is the fact that the boost readings from my BLITZ boost guage and my Power FC vary.

It's not even proportional variance.

At idle my boost guage reads -450mmhg PFC reads -350

On boost, gauge reads .5 and PFC reads .375.


I'd want to believe taht my Boost gauge is more accurate for the mere fact that at idle, it reads a stronger vacuum, and on boost it reads a stronger boost.

Where should I start checking to get the value of the PFC closer to what the boost gauge shows.

This topic is a common debate on the PFC forum. Look down the page of threads for one by serge.
