Logs are only showing 18lbs of boost but the AP says 26?

I was doing a few runs and logging just to make sure everything is fine before heading out to the track. While doing the runs I noticed the max boost showed on the AP was 26, which is right where it should be. However when i got home and downloaded the logs, it only shows 18lbs. Am I missing something here? I went out and tried it after seeing the logs and it's doing the same thing. Is it possible it's just spiking to 26 faster than the AP can log it, then holding boost at 18?

edit* I also noticed it's jumping from 87mph to 97mph , is the AP that slow in logging?

No the AP has no real noticable delay in logging. The only thing i can think of is something is wrong with the AP itself or maybe its not getting a clear signal to log the data. If it is reading live on the AP but not recording it then something might be up with your AP.

Definitely a bit odd. It seems like you simply aren't catching the 26psi values in your datalog. Power cycling the Accessport should reset the high and low values shown on the gauge screen. Do that, and then record a datalog of a few WOT pulls. Shoot them over to support@cobbtuning.com (or post them here if you wish) and we'll take another look.

Found what may be the problem. The gauge was reading "omni boost" while the log was watching "boost". What's the difference?
