Hank..what I hear is a "scraping type sound" If still there when you go to pick up..I wouldn't sign off on it. Actually tech. shouldn't release if noise still there. JMO
But, what is that noise? AFAIK..your 06 t. is diff. (part wise) than my 03. Changes made
VGT 03/06 6L TURBO Your tech. already confirmed. When mine started drying..it didn't make noise like I hear in your sound video.
Maybe t. can make that noise..or..pulley or ? Good luck!
btw..I doubt any reflash would cause noise to go away if thats the plan, but??
