Not to long ago I got my car back up and running. Ran pretty good at the track, have a decent tune in it I think, rolling E85. Not running any sort of forced induction so never bothered to pay attention to vacuum/boost, noticed it in my logs while doing a couple virtual dyno things so added a gauge to my screen. What would cause this at WOT? Here's my wheelwell profile to see the mods and im linking the pic of the screen. 7.2 pounds of boost? I make 3-5 just around town stoplight to stoplight not even full throttle, usually -13 to -10 vacuum until im past 75% throttle. So damned odd or is this just normal part of a high compression N/A motor with E85?
