Expansion Tank questions??

I recently (several months ago) installed a LET2 expansion tank onto my water heater line...(replaced one, to be more accurate).

However, my house does not have a water pressure gauge (so I did not know exactly what my water PSI was/is).

I installed the expansion tank (but did not adjust the pre-charged 38 PSI value of the expansion tank itself).

What issues may I face here?? Will I have problems if my expansion tank PSI chrage...is not set exactly to the same PSI charge of my incoming water?

Thanks

Wrong forum... however:

You can get a little Watts gauge with a tell-tale for like $10 or so at Lowes or wherever. It just attaches to a hose bib. It'll tell you what the peak pressure is. You might want to check the charge on that tank occasionally. Just shut off the water in front of the tank and then check the pressure with a pressure gauge. A bicycle pump can be used to fill up.
