mine is about that RPM too.... about idles at 700 which i love, my maxima used to idle at 2K

 

I would imagine so since the same size line is half way between the 1&2, 2&3...etc.

 

after a complete change in intake mainfold headers test pipes and exhaust mine is around 500 rpms seems low to me. I cant wait to have it tuned wait I am gonna wait for the better weather.

 

Um... My auto idles right between 1k and 1.5k rpms I think... Unless I'm remembering wrong. I have an exhaust but I don't think that made a difference

 

That's way too high! It should be down around 750.

 

yes

 

Your idle is normal. The manual states that the idle is 650 rpms +/- 50 rpms.

IMHO, I think it's too low, so I reset mine to 800. It keeps the inside of the car from vibrating, especially with the A/C on.

 

When the A/C is on my rpms usually go up to ~800 rpms.

 

I'm getting mine set to 850 RPM's with AC off after my tune

You have to let the car warm up to get an idea of what your real idle is. Just check it in between stop lights. I highly doubt you have it as high as 1.5k unless something wen't completely wrong with a previous installtion or you haven't completely warmed the car up.
