03 coupe 6 speed accelaration laggggg!
Ok so i recently picked up a carribean blue 6 speed coupe.....noticed when i kinda punched it in 3rd that if felt like i was carrying 3k extra pounds! So yesterday i went to my friends shop and got a full air induction cleaning flush and installed my JWT pop charger....but the car still feels laggy like it cant accelerate....the car only has 45k miles on it.....any ideas???
Yeah.... I agree with what he said. Our cars are kinda heavy and don't have enough torque to really sprint with bursts of amazing acceleration at low RPM's once you start getting into 3rd and 4th gear or more. 1st and 2nd gear are geared low enough that you can get away with it, but 3rd seems to be the cutoff point for that.
It's not even that....its from a start, like when im accelerating from 1st to 2nd it feels like im carrying 3 semi trucks. It feels like theres no power at all!

Check your air filler? I have a 05 and after an oil change the car just feel right...ya know?
Anyway my 05 really dose not lagg, I shift between 3-4k rpm on every gear and the power seem to be always there.

I just did a throttle body flush and installed my pop charger like 5 days ago.....there's no way its the air filter

The G35 seems to have a fairly close ratio gear set and I think first gear is almost a granny gear. Not good for dragging or off the line performance (and yet it will still do 0-60 in 5.7). Anyway, as mentioned, this engine shines at high RPMs. Peak torque is at 4800 rpm. Peak HP around 6500 rpm.
A heavy car with peak torque at 4800 rpm and a low first gear takes a good bit of work to get off the line fast. In my limited experience I find that shifting from first to second quickly (around 4000 rpm) works best for a good launch.
In day-to-day driving I shift around 3000 rpm and I seem to putt around slower than most of the minivans and Accords driven by soccer moms.
Anyway, it sounds like you need a test drive. Go to a safe, legal place. Accelerate from a stop, shift from first to second pretty quickly and run up through the gears, shifting at around 4500 rpm rolling into the throttle (not stomping it) until you get to third gear. In third steadily run up to about 4800, then floor it. It should kick you in the pants and you should be pushing towards 90 mph by the time you get to 6500 rpm. If you want to be a little more careful just do the same thing using fourth.
If it doesn't do this, and there are no check engine lights, then I'd take a look at the clutch.
