Cam dial in

Hey all, bit of  a brains trust question here. I have kelford cams that I have dialled in exactly to the specs I'm given, and my cold compression test is 170 psi. Was 145 with poncams. This extra pressure makes it impossible to tune. I have dialled them in to within 0.02mm of correct lift at 1mm degree point. At a loss as to why pressure is so crazy high. I'm thinking too much intake advance but it's perfect. Brainstorm please

What's wrong with 170psi? Why can't you tune it? What kind of turbo and ECU do you have?

You have another problem somewhere.  170 is a good number. Tuner having a brain meltdown and missing something simple thats looking him in the face? 

Are the cam gears vernier type or fixed? Need to know more aboutthe setup that was pre existing and whats there now.

Efr7670 comp was about 150 on poncams. Nothing else changed. Couldn't stop knock. Took 7 degrees out of it. Dialed up right at 165 put now will try tune it. Keep in mind 98 octane and went 420 to 350kw.

Vernier gears. Vct still there. All within 0.02mm

CAS still or? Base timing not set correctly.

Hey guys thanks for the replies. 

Basically I had specs for the wrong inlet cam. mine was custom made. So I dialled it in perfect (<0.02mm) and comp test was about 160 psi. Once I retarded my inlet 15 degrees and it was correct haha. Worked well. 600nm to redline and 400kw. It was never going to work with the old specs.
