I'm really interested in seeing the difference between the '04 and '05 torque curves.

 

me too

 

We should see this data soon hopefully.

One specific change i've witnessed so far for all 05 models is they seem to be tuned to run very rich from the factory.

 

SO if you leaned out the tuning it may be significantly faster depending on how much nissan detuned the af ratio

 

+1

 

It's not detuning, just more fuel. I'm guessing it's a safety buffer for something (maybe more timing)

 

Is the gas mileage rating the same for the 05 models as it was for the previous two years?

 

i would think so

 

Ive got 850 miles on my 05 track right now. As soon as it is broken in it is going on the dyno.

 

How many miles are you going to go before dynoing? I personally wouldn't dyno anything before 3000 miles. I dynoed my first 350Z at 1500 miles and I only put 228 then I dynoed at 5000 miles before I started my mods and I put down 241. It seems to me the engine takes a couple of thousand miles to fully break in.

 

Hmm, did not think about that. I was going to at 1200, but I might wait until my first oil change. Did you dyno yours at the same shop both times?

 

I've read that the VQ35 will put down better numbers after 10K miles when things are nice and broken in. I'm going to find that out next month when I dyno with 14K+ miles at the same place and same mods when I dynoed back when I had around 5k miles.
