So the car is running great and no more whiplash starts from an over sensitive gas pedal (trust me when you punch it... it is still a rocket).
They had it for almost a week trying to diagnose the problem. They really thought that the ECM flash would do the trick, but not for that symptom.
If any of you have noticed hard shifting/down shifting or a hesitation between gears (auto trans), then you may want to have this looked at since it was already a warranted issue with Infiniti.

***UPDATE***
After waiting 3 weeks for teh part to come in, they DID NOT install the valve body. TSB 007030 is only for 2003-2006 sedans and 2007 coupes.
BUT, they did the cruise control TSB fix, and it FIXED THE THUD!!! So, I'm happy. No more thud at 40mph, no more thud when accelerating slowly from a stop.
Maybe the CC fix is a kinda tuning "cure all" update for the 2007 sedan.

there is nothing wrong with your cars!!!! its just the way you broke it in and its not to blame you personally but it happens to do with your daily driving. since dealers tell every one dont rev hard, people listen to that and their transmission does not wear in like most people want it to.
i reved my car hard for the first week that i had it and the result is that so far i dont see that glitch as much as you guys. however, since i am driving in more and more traffic every day I will experience the same thing too eventually. because of the wearing in at slow speeds.
think about it, this happens only at low rpms and regular driving speeds. the car is trying to be fuel efficient by doing its 2-3k rmps and then jumping into a higher gear which works on producing higher speeds to the differential. what do you think should happen?

Sorry dude, but you're just plain wrong.
First of all, since the dealership FIXED my problem...... uh...... that should speak for itself. (i.e. there was a problem)
Secondly, what the heck are you talking about with "breaking in" your transmission? Good one..... Not driving your car hard will make the transmission rough. Where exactly did you hear that?
3rd, I redline my car frequently. If anything, it'll just put more wear on the tranny, not keep it from driving rough.
Your post just rubbed me the wrong way. Just because your car doesn't have the same problem, doesn't mean the problem isn't out there. Bottom line, I GOT IT FIXED!!

So l am considering changing dealerships to see if another dealer will fix this problem without me wasting money removing my aftermarket goods.
Many thanks for your inputs.

1. Not really a problem, but it was "fixed;" sensitive throttle.
2. While on cruise control, going downhill, the car would surge (kinda like playing with the gas, on, off, on, off every second.)
3. At slight throttle (20% or less) from a stop, the car would hesitate and kinda thump at around 1200 rpm. Now it's totally smooth.
4. At 40mph in 5th gear, with the TQ converter locked, if you let off the gas, you'd feel a slight thump, then slightly touch the gas and there'd be a hesitation and a more noticeable thump. It felt almost like slack in the drivetrain. All fixed now.
