The potential down sides to a 160°F are:
I'd adjust the fan temps first. Also make sure your pressure cap is good (or just replace it if it's over 5 years old), and make sure your cooling system is in proper operating condition.
Are You having issues with it overheating? Or loss of coolant issues?
- Check engine light and code for low coolant temp
- damaged catalytic converters
- higher under hood temps due to excess heat from overheating catalyst

I'm not looking to install a t-stat without tuning the car. I already installed it for my new tune from a forum vendor. The tune is not right, I can't get the vendor to respond, so I need to go back to my old tune that I'm fairly certain was not set up for a 160* t-stat. I don't want to swap my old -t-stat back in if I don't need to. That's all.

you mentioned swapping tunes back to your old one, if you are capable of doing that on your own then you should be able to adjust the tune on your own right?... if so you could just change the fan on/off temps

The fan temps are probably the least important part of tuning for a low temp thermostat. Any tuner who leads off with "I'll adjust the fan temps" is probably going to do a very poor tune for the lower temps.
The more important thing is to get the coolant temperature based fuel trim adjustments properly matched to the new thermostat. If that isn't done, you'll be pushing a lot of unburned gas out the exhaust, and that's very hard on the catalytic converters.
Also lowering the temperature where the check engine light activates to tell you the coolant hasn't warmed up in a timely fashion. Bad tunes will just set the "warm up time" timer to a ridiculously long value to prevent the check engine light from coming on due to the low coolant temp.
What other mods do you have that required a new tune?

yep, I've tried to warn people about that mess... it's not a good idea to let farm animals tune your car if you get my drift

With the first iteration of this tune the car falls on it's face when I shift above 4k RPM and the fuel mileage has dropped 20%. Totally unacceptable. Edit- To be clear: I'm wanting to put the ECS tune back in the car. I have the tune file, I was just making sure about the t-stat thing.

What a bunch of god ^*%%*T^R fu(&%^*(O bu%^&(&^^%!!!!!
This thing won't allow me to load my old tune and now my car won't start. I'm going to try this new tune just to get my car running again, but as of right now, I'm seriously unhappy. There is no way that thing should be able to download my old tune without being able to re-upload it.

One thing I'm curious about is the Corvette Forum and how the administration looks at these things. The Forum is allowing this guy to advertise and screw their members. It's pretty clear based on the comments from ECS (in a different thread) and the Forum members that it's known that this guy is a clown. I realize CF is a business not a social service, but the members are what is important, not the vendors. Guess how many vendors they would have with no members? If the CF administration won't stand up and tell people like this where to get off the bus, that's a problem.
Edit- Claim initiated.

interesting that you haven't been able to get in touch with him but I have seen him posting in threads after this one was made... I have dealt with vendors like that in the past and it is very annoying, they put all their effort into hustling people to buy their product but are ghosts when it comes to actually helping those people
