I've had my '04 6sp G35 Sedan for a couple years now. Been on the site a while, just never posted. I recently bought an Uprev Tuner and I'm finding very little info on the G forums so I figured I'd try my luck here. Right now I've just been making small changes to the tune, mostly bumping up fuel at WOT since it's running lean (pretty common with bolt-ons I guess).

My G35 is a daily driver/baby hauler, with just a few small mods I was able to sneak past my wife. Z-tube, plenum spacer, testpipes, coupe midpipe, 19" G rays wheels, and 350z springs.

I've got an ugly beat to crap turbo '96 miata for my "fun car".

 

Welcome to MY350Z.

 

Welcome.
Nice Miata!

 

Welcome!

 

Thanks for the warm welcome.

 

How did you sneak those wheels past her? lolz

 

Those she did notice, but I made sure she knew those were coming before I even got the car so I guess they got a pass.

I ran a couple logs through VirtualDyno and was pleasantly surprised with the results (numbers are somewhat arbitrary since I had to play with the software as there wasn't a "manual" option only "auto", but the gains should be pretty reliable). It was ~14:1 at WOT when I started, bringing that down to 12.8:1 really picked up some power. I'm anxious to start adding timing.

Thought this was an interesting overlay with my Miata, kind of funny how similar the peak numbers are. The G's powerband certainly looks a lot prettier though.
