With an 08 it unfortunately means that you need a Tactrix cable or a COBB accessport to tune.
Who did you buy the car from? they should be able to tell you if their is a tune on it.
Protune done by a shop is typically in the $400 - $500 range
Tactrix (170) + etune (175) = $345
Cobb access port + etune Usually the access port alone is around $400
The SPT will mate to a stock downpipe.
