MIGHT be a repost but it helps newbies

i was always wondering what my #'s are in psi when i read the pfc commander.

for any of you who wants to know what psi there running

take the number shown on the PFC .98kg/cm2 and multiply by 14.194=13.9psi

Except 1 kg/ccm2 = 14.22 psi; thus .98 = 13.94

doesnt the scale and offset correction for the map sensor put that to rest?

It can. The default scale and offset values are poor. The greater the boost the more the error. I selected different scale and offset values with the stock MAP and now my PFC relative boost, PFC absolute boost and my VDO boost guage all agree. It's not that hard to change but the downside is some retuning is needed.
