Hello guys I have an up rev tune on my 2004 350z coupe (AUTO) should I stay in manual mode? It seems to drive fine in normal conditions but once I press the gas a lil more than half way the car sometimes can't figure which gear to stay in unless its a straight away. Do you think using manual mode, which I found does a better job since I get to hold onto gears would be the right way to drive it? I guess I'm more of not used to it being rev happy or its just trying to stay in the higher gears to stay efficient. And I don't believe the turner screwed up the tune cause he's very knowledgable with these cars, all he does is GT-Rs, 350zs, infinitis from G35 and G37

I don't understand why you have an upgraded fuel system if you do have force induction but unless you're really pushing it I would just stay in auto for fuel economy reasons.

 

The previous owner had it boosted apparently judging by the injectors it was the Greddy kit with twin turbos
