Tuned ones have a tendency to drop #6. Call any local audi shop and ask them what they think of the EA839.
Edit: Here's some info form 034;
Their tune in particular seems to pop #6. |
No.
All EA839s are the same in the same way all B58s are the same.
EA839 comes in 3.0T and 2.9TT variants.
Vehicle applications have obvious differences for example intake ducting, exhaust routing, and tuning. Standard practice for all brands for decades. Old news.
Early EA839 Audi builds had cam roller failures. After MY19 nearly zero of these failures have been reported on Audi or Porsche forums.
