it will depend on the issue.

If my tranny blows i have an mr tranny and tranny control unit ready to swap in.

 

how much did the install at the dealer cost you? i'm not sure if i can take on the turbo swap myself... thinking of taking it in to a shop. Would you guys say get the tuner to install it, or a dealer?

 

i'd honestly never get a dealer to install something but thats because i'm a cheap a$$ and do things myself.
With that said. If they're willing to do something like that and still keep your warranty in tact hey it might be worth the money.
