Vacuum/boost gauge reading vs E01
This is strange. My mechanical vacuum/boost gauge reads -30 at idle, and goes up to -20 under light throttle. At WOT, it goes up to about 0 psi, or maybe +1. Also, when the car is shut down but the power is on, the gauge reads about -18 (I thought it would go to 0).
However, the vacuum/boost gauge on my E01 reads -8.5ish at idle, goes up to about -5 under light throttle, and at WOT was going up to +10 psi (yikes!).
Any ideas on the disparity between what the E01 is reading vs what my mechanical gauge reads?

Sonds to me like the E01 is more accurate. I am waiting to install my turbo, but in the mean time I have the E01 already installed. At idle there is about a -8 to -10 psi vacuum, which is what you are reading with it. -30psi is too strong of a vacuum to be realistic.
You should connect them to the same port and then check the readings again.
