The thing about those $20 "performance modules" on ebay, is that if someone is dumb enough to believe their claims, they are usually dumb enough to disregard any advise against buying and installing them.
Even then, they are not stupid enough to come here and ask us how to fix their rough running engine and make the check engine lights go away.
....though there HAVE been a couple who bought one, then had the ballz to complain that nobody here would show them the "right" way to chop it into their wiring!
(Why would the remote start not be an option for you? You just need an installer who will put one on a manual tranny car.)
