so I'm looking to get a software tune/ECU to get better performance. Done some research on the forums and read about the osiris UPREV ecu/tune to be the most common one used

what would you guys suggest to purchase for software for my stock g37, don't have any mods yet but am planning on getting intake and exhaust.


thanks in advance guys

 

advice! get all your mods installed before any tuning. you can go to Uprev website and find your local authorized Uprev tuner in your area.

 

There are tons of threads on here comparing UpRev and Cobb, please do a quick search
