P0401 EGR Flow Insufficient fix?
I searched and saw the fix was to check for a loose hose. is there anything else anyone can suggest? I have not really noticed a lose in power. I don't beat or go hard on it. Pretty much babied so I can't tell if there's a drop in power.

The only way for you to find out a loss in power is to gun it. Do you have a boost gauge?
Most likely you blew a hose off. A quick cheap fix is to get some zip ties and clamp down the two nipples on the egr valve behind/under the intake manifold.

I had this problem after my transmission was re-built and put in. I had my hoses checked and my valve replaced. Only to find out that the plastic nipple had broken off in the hose! So when you are checking your hoses, make sure there isn't a shattered plastic in it, which was my case.
good luck

there is an "octopus" of Vacuum hoses which run all over behind the IM and connect to the two ports on the top of the TB, if you find you need anything from this setup let me know as I have all of it. typically the vacuum line comes off of either the EGR valve itself or the one way check valve in the large line is clogged or stuck closed. Let me know if there is anything I can do to help. I just eliminated my EGR system all together and modded the ROM so it doesn't throw an SES light.
