A/F at what rpms should 11.5 be maintained(predator custom tune)?

[Scotts 03 COBRA]

I will be installing the predator custom tune and taking the 03 cobra to a dyno--At what rpms should the A/F I be looking for to maintain the mid 11s(CAI and CAT-BACK are my mods)--eventually I will be installing 2.93 non slip pulley with a new custom tune for the predator--should mid 11s(a/f) be maintained at the same rpms as before? Thanks for your input

at most 4500 on it should be below 12. Mine is 11.1 at 4500 and it slightly goes back up to 11.5 at redline. I have a custom dynotune from Apten!!!

That is exactly what my tuner recommended with my Predator pulley tune. Get below 12:1 by 4.5k.

My tune goes below 12:1 at 4k and gradually drops down to 10.7:1 at 6k. It raises slightly to 11.2:1 at 6.5k.
