Greddy profect b II, boost not matching.

[GSXNUTZ]

I installed the profect b II this weekend and took it out to dial it in and noticed the boost showing up on the boost controller didn't match my boost gauge. The boost controller would show around 12psi and the boost gauge would show like 19psi. I'm not sure what's going on and would appreciate any help. also it threw a code the first time I turned the car on, I'm sure it's cause I'm not using the stock boost soleniod but if anyone knows how to get it to turn off don't be afraid to share the info! I have a 99 gsx, if that helps any one.

Thanks, Josh

My profec e-01 would read about 2 psi lower then my anolog gauge, but they both zeroed in the same place, I had my e-01 gauge tapped right off the wastegate and my Autometer gauge tapped at the throttle body, so maybe that was why. Just letting you know you are not the only one with this problem, but to be safe, I would trust the gauge with the higher reading.
