aksed my dealer about timing advance
I have a P0420 code that I need TSB done for. I also asked about doing a timing advance. Service guy said they will not do that, that they leave everything as factory set, due to some liability issues.
I will try another dealer, but it's 30 minutes away.

dont talk to the service manager or do it "on the record"
when i got mine done i talked directly to a service tech when he went out to get another car. gave him $50 and he did it. both of us won.
josh (irish44j) and I got our's done at the same time)

like sooner said, just find a tech out taking a smoke and slip him some cash to do it real quick....
make sure to bring the programming instructions (posted here someplace) to show him when he tries to say "I don't know how to do that" etc etc...

though, "incredible" might be a bit strong of a word

Shame that the 3.5s don't experience this as much as we do.

Sometimes I like to credit myself for helping to really bring the timing advance craze to the masses. I've gotten well over 200 PMs asking me about it and where to get it done.

Does the fuel economy decrease?
How much extra HP do you get from this on VQ30?

For the time I’ve been a member it was not discussed for sure. Besides, it’ll take at least 20 minutes for me to find this info and someone who knows it can type it in 20 seconds…
So if someone knows the answers to my previous post please let me know.

Fuel economy actually increases as long as you only use 91/93 octane. But you probably won't see much of an increase since you'll likely develop a heavier foot from always wanting to feel the increased surge of power -- I know I did.
On 3.5Ls it doesn't make much of a difference because of how the 3.5L was designed. 3.5Ls are more prone to engine knock from low grade octanes than the 3.0Ls, which might mean that they're already running a certain timing that'll create knock easier. 3.0Ls will require a lot more abuse and poor octane to begin knocking.
Err...I guess if I'm not coming off clear, let's put it this way: the 3.5Ls 15-degrees is like a 3.0Ls 17-degrees. So when 3.5Ls are advanced it doesn't do much for them, because they're already built from the factory to spark quicker/early, where as 3.0Ls have to be advanced to do this. This is what I was told previously by a Nissan technician. It sort of makes sense* once you begin to consider the frequent engine knock issues people have with their 3.5s.
*Edit: I have NO idea how I wrote "noise" instead of "sense".
