How do you tune a Z-car?

If you want THE BEST results from a tune, nothing can beat a dyno tune. These hand held products are a great idea but they have been pre-tuned with estimated changes according to your mods.

UpRev Osiris is an amazing software that should be released for the VQ37VHR very shortly.

The Cobb AP has this feature also. Sure it comes with preprogrammed tunes but you can also take it to any dyno shop that has AP software and get a custome tune for your car. What most Suby guys do is run the stage 2 tune from cobb and then later take it to a dyno shop to get a custom stage 2 tune done. So the this particular hand held has the best of both worlds. For those who don't want to fuss you can just run the predone tune from Cobb and for those with other mods or looking for more power you can use your Cobb AP to get a custom tune. Also people forget that the cobb AP is more than just a tune, it has many different features that most car guys would like to have.
