question about silicone hose job and solonoid testing
I have all the hose & accessories from hose techniques for a complete replacement and a mityvac to test the solenoids and check valves. My question is if I have a 10-8-10 pattern and all seems to be working well do I worry about checking anything and testing solenoids and check valves or do I just replace the hoses and move on? My car has 42k on it and seems to be working well but while I have the UIM off I don't want to miss an opportunity.
Can any of you suggest what I should replace while I'm at it? I just want to be efficient and do what needs to be done, but not waste money replacing everything if it's not necessary. Any advice would be appreciated.

If everything is working, I'd almost suggest leaving everything alone. 
However, if you are going to tear into it, I would see about replacing the OEM check valves with something more robust. Dale Clark has been selling some beefier check valves for a while so you might ping him about those.
I would also check the PCV valves, especially the aluminum one as it tends to absorb heat and fail quite a bit. You could probably ignore checking the solenoids, but it probably wouldn't hurt while you have everything apart.

ditto, if it ain't broke then don't fix it and create more problems. just be sure to use a heat gun on the OEM hoses while pulling them off, it may save you a solenoid or three.
it's difficult to test the solenoids properly anyways because they tend to leak boost more than under a vacuum test.

Change the check valves. It is a quick and easy process.
However, I would not touch anything else if you have perfect 10-8-10 boost pattern. Though, I would make an exception if you are due an FPD change.
