The moment I drove off the lot I could notice the difference. I mean it is now more response and feels like more up off the line. Did they do the 0-60 test with or without the new upgrades b/c i bet it makes a difference.. ATLEAST WITH ME.. I AM SOOOO HAPPPPYYY

Dont get people all hyped up. I got it about a week ago and there is hardly any difference in response off of a stop. There is noticable difference with reaction in acceration at higher speeds but the acceleration off a stop is hardly noticable and I guarentee any 1/4 or 0-60 times would be greatly effected.

For the Umpteenth time .. THERE IS NO RECALL!! IF YOU ASK YOUR DEALER ABOUT A RECALL THEY WILL OBVIOUSLY SAY NO. It is an update to existing parts as requested by the owners need.

From what I have seen... IS's react and drive very differently. Some a lot quicker than others. Maybe the ECU Updates will have a varying effect depending on how fast your car was to begin with. That can explain how some say WOW!! and some say HUH.. WHAT DIFFERENCE?? It's all relative guys.
