Performance on Stock Revup
It's really weird that you guys mention the getting gas thing - I had noticed it before, but thought I was just being crazy. In fact, this is the first time I've ever seen it mentioned. I can't imagine there's an aspect of the RevUp that makes that occur.
My only guess regarding that is the fact that gasoline slowly loses its power over time through evaporation and what not - I'm not sure of the exact physics involved, but it's along those lines. That's why it's said that you shouldn't have gasoline 3-weeks or older in your tank - it just loses its energy. So if you want a suggestion along those lines, only fill up your gas tank to a little more than you'll use in 3 weeks.
As far as the lag goes, I've picked up a bit of lag in the throttle response, but nothing severe. My big thing is that the tach will stay up for a little while after I let go of the throttle when it's higher than 3K. My brother, who owns an 03 G35c has been completely perplexed by that. I've just adjusted. With all my mods and worn tires, I broke loose gassing it from 35mph in 2nd, so the power/torque is certainly there.

I tried that a while back, to no avail. The throttle lag thing (where the tach momentarily hangs without falling upon let-off) is a really peculiar, as it seems to very distinctively stop acting that way below 3K rpm. It's almost like it's that way by design.
hmm well your comment about gas, i get gas every week so its not that old.
I dont know what procedures i should take because it really feels like a different car right after i get gas. Throttle is resonsive and you can feel the acceleration oposed to normal driving days
Maybe illt ry resetting it? I noticed my MPG has also came down and i dont drive the car hard. I used to get 20-21

Mine does that too. The older 05's I test drove without the revup did not seem to do that.

1) Nissan approved compression test
2) Clean air filters including MAF sensor.
3) Check all hoses, grounds, etc for proper installation or ruptured lines.
