Rough Idle with High Pressure Crossover

So, I just installed the KCM Stainless Steel High Pressure Crossover line between the 2 rails. I know it is supposed to help with rough idle but this mod actually made my truck idle more rough! and, it doesn't seem to have the power it used to have either. doesn't pull as hard. any thoughts as to why?
thank you.

It's usually just air left in the system.

Sold 2001 f250 ccsb 4x4 400/400, dual terminators, swamps 80mm bfh, headers, bts and all the usual supporting mods. 715hp fuel only.
