Greetings folks, I'm currently on the original ECU map with the more aggressive throttle response (the sensitive throttle tip in doesn't really bother me too much as ive learned to manage it) I'm wondering if I should get it reflashed to the one from service bulletin ITB08-017, released in May 16'th 2008 For the 2007 G35 Sedan with Auto only.

Now normally I wouldn't bother, but I am getting a noticeable hesistation at 1000rpm (seems to be a common issue) and sometimes the tranny does some weird things, ie, downshifts way too much at part throttle or seems to hold back power in first/second gear.

So I'm looking for opinions on which map drives/shifts better. I've also heard of improved mileage with the newer flash?

I suppose my other option is purchasing a license/cable and getting an uprev Osiris tune, although my car is bone stock except for K&N drop in filters.

Thanks in advance for any thoughts!
