Evo 9 Pull and knock problem

So I just got EvoScan and Cable and everything, and my evo IX has been knocking whenever i go WOT. My boost Gauge shows my boost limits at 19-20psi. Im looking at a CSV file and its showing for my MAP Boost numbers in the 10-47.5 range.

While in 3rd and going WOT my Boost gauge shows 20 psi and my Knock CEL blinks the whole time and once i hit 5-6k rpm it does a boost cut.

What problems could i be running into?
Is it to much boost?

I cant even go WOT without Knock CEL Blinking

Who tuned your car?
And are sure it's blinking the whole time and you still go WOT until boost/fuel cut?

Not sure, i bought the car from dealer. But this morning i turned down the boost from 20 to 10-15 and im able to go WOT and no Knock/Misfire CEL blink.

Good. I suggest you have it tuned before doing anything else. Keep the boost down until then.
