I had an Uprev for my VQ35 HR 5 speed and did tweak it a bit using the tuner version. The only huge improvement that I noticed or felt regarding a firmer shifting of tranny is when I totally changed the ATF via pan drain plug and cooler line. Proper amount of ATF was added at 70k miles. ( I did it in my garage) Huge improvement! When I shift this time, there is a little force that push you forward not hesitating or lagging using manual mode.

Right now I have a Q40 with Ecutek, etune is not finish yet, still the car shifting is not firm if I drive it less aggressive (below 3.5k rpm). Also, there is a bit engine strain when you gun it. As I said it before, John Visconti is not done with my Etuning. We are still on MAp 3 revision 4. He has a lot of catching up to do...
