Finally got my EGR Plate Blocker installed. This was a major
PITA!!! Needed to get as much stuff out of the way just to get to it. Get the heater hoses (2) out of the way...it helps out allot.
Noticed some major turbo whistle after blocking the plate. And maybe, perhaps quicker turbo spool up.
This project on the LMM...is not as easy as some people would lead you to believe, but for me it seems to be worth the little gains it provides
