I want to know what the best idle is for an A I cam 568' 569 lift would be. Should i just keep it a 1000rpm. Are what should i lower it to to get that distinctive rumble but without making the car struggle to stay started

 

The 'best' idle will depend on the whole build, but I'd say you'd be safe to make a jump down to 800. Then from there just adjust in increments of 50 rpms until you've reached what you want.

 

my main mods are in my sig so how do i turn the idle down

 

and will i have to have it retuned if i turn it down

 

you'll need it all re-tuned to make sure it runs right, you can do it youself with a hypertek but if you have already had it tuned because your running a charger you dont want to wreck that. if the car itself runs right up the rev range under WOT i would leave it or get it done by a proper tuner

 

R&D is your friend start playing with the iddle untill you get where you like it and is drivable
