So just got another G35, 05' 6mt, has a stillen cold air intake and Basani cat back exhaust. Looking to retune make this thing come to life a little. Looking at the Osiris tuners, guy has a used one for sale right now. Or is there something better? I've been out of the G game for a sec.

 

Osiris is proven to be the best for NA applications.

 

+1 Osiris is the only game in town for NA tuning... the choice comes down to whether you want to get the tuner version and mess around with it yourself or go with the standard version and have a professional tune it for you (me)

 

Or Both <Me>
