Harlan RPM switch

Post by unleashedcc » Wed Jul 13, 2011 10:04 pm

I'm in the process of installing my r/t intake manifold on my 02 ATX. Now, I know the butterflies kick-in at around 4500rpms, since i'm ATX i was wondering, would it be smart to program the Harlan switch to activate at 3500 or 4000rpms since i usually dont hit 4500rpms in my normal day driving?
