what should the idle speed be with a A4 after you have installed a 224/224 with headers and is it normal for it to be a little rougher at first when its cold.? oh, Its a 2002 t.a. and I did have it mustang dyno"d.

 

Its going to idle low,I believe mine idled at around 500-550,and it used to die at every light.You will need to get a tune to turn the idle up.And yes its normal for it to run rough when cold.Welcome to having a cam.

 

yea, I did have it dynoed right after , and it idles around 800-900 and it doesnt stall.throttle response is tremendous, especially with my 373 's and my 2800 stall.also is it common for it to smell a little rich at first when its cold.no smoke or nothing just a little more richer then when its warm.

 

What did you dyno? What lsa did you go with?

 

it dynoed at 436 chp and about 360 rwhp, and it was done on a mustang dyno.

 

What other mods do you have besides the cam, 3.73s, and stall?

How did you raise your idle? Drill the TB hole?

 

kooks headers, corsa exhaust,jantzer ported t.b.,slp ramair kit,trans-go shift kit and 160 degree thermstat.
