I have a Trickflow track heat intake for a 5.0 and installed it this weekend. I am wondering if any one has one of these or a streetburner on thier car. I was wanting to know if the plenium wistled. I have sprayed eather around it and no leak. Plus now its surging between 800 and 1000 rpm. Do I need to take the egr part/section off the throttlebody? If anyone has any idea let me know. Thanks
