Profec B Spec II vs Autometer Ultra Lite

[geetee]

Hi,

Any thoughts on this welcome.

What's more accurate, the digital readout on my Profec B Spec II or my Autometer Ultra Lite gauge (mechanical product ID 4301)?

Reason I ask is that in the lower gears (1 & 2) I'm seeing the gauge whip round to about 20 psi (which is 1.38 bar) then immediately settle back down to about 17.5 psi (just over 1.2 bar) which is what I'm looking for.

The Profec shows a Peak boost of 1.22 bar.

So either the Profec isn't picking up a boost spike or the gauge movement is under-damped and overshooting because the boost comes on quicker in 1st and 2nd.

I think it's the gauge overshooting personally, it's literally a fraction of a second.

Any ideas?

Thanks
Graham

I get the same. I think you're right about the gauge overshooting.

I'm still fannying about with the settings on the Profec B to try and iron out the bloody spikes in 1st and 2nd, when the turbo spools up really fast :evil:
It's doing my head in :roll: :lol:

Graham, what are your current settings and do you still have the standard turbo?
