I always drive with the VDC off, Still SSLLLOOWW on the line ,LOL Till I ramp up I had a DAMN Mazda SUV stay door to door with me:shakes head:

The power (HP) on this engine at 2k is about 75hp. and at 3k about 125hp. If someone in a mini van just floors it at a light they will easily be putting out the same or more power if you just go with a nice smooth start in the hi 1ks low 2ks rpm.

:shakes head:

depending on your launch rpm's and your light timing ;)

The 350Z definitely has better response down low. It is whiplash inducing. With the 370Z I had issues blipping the throttle on downshifts because it wasn't as eager to rev when I tapped the pedal. On the 350Z, it was easy to blip the throttle and get it revving past 3k RPM. It's all in the software from how I see it.

The symptoms posted in the "Gas Pedal Delay" thread are EXACTLY what I am experiencing. Reading through that thread, tells me that this isNOT fixable, especially since I live in AZ...where nighttime temps are in the 90's. It didn't appear any of the top tuners had come up with a 100% solution?

PedZ...did you ask specifically if there was any additional tuning they could do to 100% eliminate this issue?

I did not. I main goal from the tune was to just get the car running as best as possible.

Im curious if its just related to oil temp...do you have an oil cooler installed? I notice this happens to me when oil temp reaches 220 and above (doesnt take long 5 minutes driving in town). it lags when in first, and the revs 'hang' a bit after coming off the throttle. this year I switched to red line oil and installed my gen3 intakes , I dont remember it being as bad last year but it could have been...Im hoping to install an oil cooler this summer, and maybe insulate/heat wrap my intakes. I've noticed slight lag in the past and considered getting that sprint booster, but now its seems much worse especially when the oil gets to 220 so I dont think that would solve this issue.

No oil cooler installed, but yes, I believe it may help. Being here in AZ, I hit 220 within 10 min of driving in the afternoon. I notice in the morning, the car is less likely to have the delay when the oil is cool and the temps are lower.

This is just truly frustrating...can't believe that Nissan, nor any tuners have developed a 100% solution...

I think I noticed it more when I installed my Typhoon air intakes. But it definaltely happens when oil temps get hot. 180+ I hope to get a tune soon and I hope this helps fix this issue.

wow, well im in northern Ontario Canada and my temps still get up fast under normal driving. there maybe something else going on, but Im gonna start with the oil temp, then maybe a tune (uprev now has rad fan speed control mod) hoping these will resolve it. I was saving for springs/spacers, but it seems that fund is now going towards the oil cooler ...

it's got to be related to engine temps and intake temps combined. I had this problem until I got my oil cooler, and tune with the radiator fan control. with the oil cooler alone the problem was still present. now that a tune and fan control has been done, I have had no issues with the throttle lag. oil temps never get above 200 even with aggressive driving.

Which cooler do you have?

Does anyone get this BOGGING with stock airbox or CAI like Stillen G3?

I am thinking it might be heatsoak that causes this.
