Would it make sense to remove that area of the plate that covers the EGR passage if you are using an intake with the passage removed or would that change the characteristics of flow that the P/plate was designed for in the first place?
Was there 2 versions of stock P/ Plates? I seen one for sale today that has a square hole for EGR & doesn't look homemade, & if running a ported intake with EGR passage removed should plate be trimmed to match opening?
