So I'm going to get the g tuned this summer. There is a tuner about an hour away with a Awd dyno but no experience with nissans vvel. So would it be better for be to go for the Osiris standard? It's 500 bucks and seems to be uprevs version of the accessport

 

Don't know anyone using it, but I'm also looking into it since the closest tuner in over 6hrs away... I'm talking to a local tuner that's checking out the uprev tuner to see if he feels capable of producing gains. The guy has great rep with tuning skylines and GTR but he's never done a G37... If that doesn't work out I might go with the Standard...
