eg33 swap overheating

So I swapped my impreza with an eg33. the eg33 is using the griffin radiator and a morosso inline coolant cap with 20lb cap. Using twin 7 inch fans. So if i drive the car itll get to 220-230 very fast. heres what i've done so far and still cant figure it out.

-Burp the system many times
-new thermostat, run no thermostat
-pull water pump to make sure all is good
-coolant compression test, holding pressure just fine at 15lbs
-no signs of white smoke or coolant/oil mixing
- using temp gun measure temps and the block is indeed spot on with my aftermarket coolant gauge.

the car will idle to about 195/200 but the second i start driving it gets up to 220/230. Anyone have some advice?
