I am still debating which UIM (SE or SVT) to send. I see you have decided to send an SVT after the SE was finished. Why? Do you have any data from Rick (flow #, size of t.body opening, size of runner openings afer the process)?

I have looked at the SE t.body opening and it looks like it could open up to 60-62mm to match with an SVT t.body and not impact the EGR. Note, it will still be smaller than stock SVT t.body opening as that is about 65-67mm. However, unless you are planning to use a 65mm 4.6L t.body, the SE "should" be OK for the SVT t.body??
