Got a Greddy Profec Spec II
Got a Greddy Profec Spec II
Well, I picked one up off Ebay from a guy named Dennis. ID is Autowurks. $309 shipped so price was good and service was too.
It works really well and has some great features but I've got one complaint. The display and all settings appear to read 2 PSI higher than both my Autometer gage and Haltech. Even with Autometers reputation, I'm pretty confindent that the gage and Haltech are fairly accurate. SO.... Any experts out there know of a way to adjust, maybe by an internal var. resister, the reading to make it accurate? I'm a little gun shy to just tear it open so soon....

Only complaint was that with it reading 2 psi higher, I had set the "overboost" limiter too low. I was originally fighting the unit's own limiter function and boost was bouncing up and down. Now that I've compensated for it reading too high, it works great.
Have you stopped to consider that you likely have 2psi drop across your IC and pipes? Its very likely, especially considering that the boost controller doesn't know what the pressure is in your TB, only whats at the compressor.
