Hello, I'm fairly new to the 350z world. I bought my 2003 base model this summer and have added a pop charger and md spacer. I have some questions on flash tuners.

1. Are there any independent dyno runs using the cobb accessport preloaded maps?

2. I see alot of the tunners raise the redline 500rpm or more, seen somebody say they can run 8k stock. Is the motor really that restricted stock that it can safely turn those numbers without harm? And will the stock cams and plenum with a spacer even make any power above 6k as i seem to feel the power drop as i approach stock redline?

3. I know not to do a dyno tune till I am finished with my bolt ons, but is it worth my time to etune the car with such minimal mods?

Thanks

 

id do it. the more bolt on more power.. but u will be lucky to get 280hp with bolt ons save as much as u can and get a used turbo kit trust me well worth it....

 

A tuner can bump redline 500 or 1,000 RPM. He may want to do that to push horsepower a little higher. If you have, say, a 7,800 RPM redline, you don't have to shift every gear at 7,800 RPM.

Is 7,800 RPM as safe as 6,800 RPM? I think you know the answer.
