I have mine at 7850 I just did it for the heck of it Im not sure if it lets you go up any higher. Ill check on that. No its not specifically for nissan 370 it works for lots of other gas cars but when you select your vehicle it downloads the tune specifically for the Z and nothing else and marries your vin and verifies its a Z. When I got it I selected the car then updated. thats when it got the new files for the nissan. I dont know exactly what is live feed is but I think this one is like they said, its just a cheap tune that their nissan tech put together and you get whats there. You can change a few things and but they are also limited to how much you can change it. It does read your stock files and saves them to sd card and dowloads one of the tunes (whichever you chose). Im not trying to convince anyone although it might sound like. Ive had two and I can say it does change the vehicle it thinks it cleans up the table. now power gains I cant promise anything. I dont work for bully. Ill be going to the dyno next week and post pics and maybe a vid. So we all can find out if I just wasted couple hundred of dollars. Lol! Uprev i had never heard of it or know how it works Ive heard all kinds of good things and a few bad like everything else. Can uprev be completely removed for warranty purposes? Or is it like Trifecta we need to have the cable in order to remove it? Does it void warranty? I know nissan does with the bully dog. But it can be removed in matter of 3-5 minutes, but if nissan sits down for a for a few hours I know for a fact they will find that the computer was accesed without authorization. Easy removal and past experinces is what sold me thats it. Sorry for the long post.
