just got a great deal on 2011 4dr 3500HD 6.6. 200,000 miles. [$2500] in limp mode. Deleted it and drove it. Ran great!
noticed slime in overflow tank. Too busy so I took it to local GMC and they wanted $450. For a flush out. told them it was deleted and they said they couldn’t take it in. Went down the street to a Chevy dlr and they gave me a $350 price. OK
told them it was deleted if that would be a problem. The service advisor told me that he encourages deletes. Great
picked it up today and it blows black smoke and runs like a 7.3 idi. Very slow! Can someone give me some advice?
i did not do the delete, paid someone.
