Bypass valve install success stories? 5ktq

Is there a Samco application for a 5kcstq that includes a place for 
a bypass valve?  

I thought there was such a hose, but only for ur-S4's or something 
like that.

The only Samco hose I'm familiar with for the 5kcstq is a regular 
replacement fo the Michelin Man hose, except that it's not, um, "Q-
shaped" for the funky throttle body, and it's challenging to install 
the firm round cross section hose onto the "Q" shaped throttle 

However, all I know about Samco hoses comes from perusing the 
'net, as I have no direct experience with them.

I'm not sure if the "plug" looking thing you refer to is the same thing 
that Peter drilled out when he installed his bypass valve.  In any 
event, his webpage describing how he installs his valve is pretty 
good.  It's here:
