03 Mustang RPM's Hang Between Shifts (Manual)

[tonygug]

I have a 2003 Mustang V6 3.8L 5-speed with a Pypes Performance Complete Converter-Back Dual Exhaust, a K & N cold air intake and Hardcore 8mm 0-ohm wires set. After I installed the predator performance tune the engine’s RPM’s seem to hang around 3000 RPM’s between shifting. Also when I stop it takes a few seconds for it to come down to the Idle RPM setting. I have Predator model U7146.

Any Reason Why?

Thanks

Should I lower the Rev Limit in Neutral, wil that stop the RPM's from hanging between shifts?

Has anybody had this problem before and what did you do?

Thanks
