Question New Intake on 5.7l Hemi w/MDS Question

Hey Guys and Gals,

Last saturday i installed my new K&N Cold Air intake system on my truck (Aircharger 63-1533).
Well so far its been up to par on what its stated with increased performance.
So my questions to you guys and gals is when im crusing on the freeway doing 75mph, my RPM drops to about 2,000RPM. So i guess thats when the MDS is kicked in. But Since ive put my intake in, every couple of seconds it raises the RPM to about 2200-2300RPM. I dont know if this is bad or if its ok for the engine to do that, fluctuate back and forth?

Please let me know i dont want the intake to mess up my engine.

Tama

I have an AEM Brute Force intake and I don't have that problem. I wouldn't say it's bad but I'm not sure why it would do that.

i have the K&N 77 series (till my ram hammer gets here) and I never had that problem and most my driving is highway miles

Edit did you reset your PCM? so it can learn your new airflow?

When thr RPM increases that's when the MDS is workiing. When the RPM drops it is back in the V-8 mode. If your doing 75 mph MDS is going to cycle back and forth alot. Try slowing down to 65 to 70 and see what happens.
