2007 335 coupe lag/jerk?

So I just bought a 335 auto coupe, I am coming from a auto 2006 nissan 350z. The nissan had immediate throttle response, one mm in on the throttle and the wheels would catch, very smooth and predictable power as the slightest adjustment in the throttle the car would reply.

I am noticing with the 335 when I first begin to push the throttle, it does not catch right away, like the first inch nothing happens. Then after that it catches, but it doesn't feel like it's smooth or powerful around the 1.5-2k rpm range, kind of like a little delay in this range and then a little bit of a jerk when it catches say around 2k rpms. This is the best way I can describe it. I think I am just noticing the difference from the z to this car, but I am worries if it could possibly be a transmission problem or if it is just normal for this car. Thanks guys!

Drive by wire, turbo lag, turbo not holding boost?

turbos dont spool up untill about the 2.5 3k rpm range put it in manual and ride in 2nd and let the rpms sit at about 3k and floor it n see how quick your head goes back in the seat.

Drive by wire - everybody experiences this, and it's very noticeable coming from a different platform.. has nothing to do with turbo spool, and its not your transmission.

It's normal, my other car is an Infiniti fx with VQ35 so I know exactly what you're experiencing.

Thanks guys, I figured it was normal but just wanted to confirm. The Nissan 350z was just so throttle sensitive so this is just going to take time to get use to.

May want to get a walnut blast as well. Car is infamous for carbon buildup. Just got mine done and it has helped with throttle response and my occasional stutter.
