Subject: only getting 1.7 bar of boost

Hi all,
I'm in the process of working out all of the little gremlins of my new(to me) 91 200 20v. I'm attacking the boost situation first. I went to Scott Mockry's site and have done the ABC's, I found that my WG frequency valve was bad... I've replaced all vacuum hoses and before installing the WG frequency valve I was only getting 1.4 bar in 3rd gear WOT. I now am getting 1.6-1.7 regularly I will occasionally get 1.8 in 5th gear at WOT. Is this normal???? Or should I still be looking for something else. I know that altitude and fuel quality have some say so in how much boost is created. I live in Milwaukee, Wi and ONLY run 93 octane in the car. 
    I almost forgot...I installed a manual boost gauge and when the digital gauge reads 1.7 the manual gauge only reads 12psi. I haven't done the conversion, but does that sound right as well???  I want to get all the bugs worked out before I send my ECU in to get modified. Thanks for any help !!!!!!
