2003 with turbo lag
I brought home an '03 6.0 last night with 140,000 miles on it. It was a "one owner" truck that hasn't seen hardly any towing or work. It is all stock and is in good condition. It's got stiction on cold starts so I'm hoping some oil additive will clear that up. On acceleration, it seems the turbo is very slow to spool up. There is no codes at all so I'm figuring the VGT vanes are probably coked up and are unable to move freely causing poor acceleration. I've driven newer 6.0's ('05-'07's) That spool up much faster. Will a 2003 turbo spool up slower than newer ones because of having less vanes? Any other input would be great before I remove the turbo to inspect and clean it.
