Review on Innovative Performance Programmer Subaru Legacy by Patrick Reynolds

Revainrating 5 out of 5

Doesn't help improve engine economy

Installed and found no improvement. Follow their recommendations and disconnect the battery for more than 36 hours. And haven't noticed any improvement in fuel economy, throttle response or gear shifting.

Pros
  • Great for me
Cons
  • Some difficulty
