Hi,

I am tuning a M6 camaro 98, the camaro has got new cam, polished heads, new injectors, and exhaust system.

The car will be for street challenges only, so the close loop mode will be off all the time, and sure there will be no fuel trimming. The tuning will be mafless only. The VE table looks fine and the injectors are corrected, but when the car in neutral the RPM doesn't come steady, it keeps moving up and down.

1. Therefore, what should I tune further?

2. If IAC vs area comes into the picture, how it should be tuned and why?

3. If desired air flow comes into the picture, how it should be tuned and why?

4. If throttle cracker comes into the picture, how it should be tuned and why?

5. If throttle flower comes into the picture, how it should be tuned and why?
