think thats it,
I had my buddy, who is a mechanic, check the hoses. Everything looks normal.
Maybe I should get it smoke tested/pressure tested? Anyone know a good place?
Why would it idle fine before I clean the MAF, then idle crappy after cleaning?

As everyone has already said, you likely have un-metered air coming into the system after the MAF.
And while you think it is running fine on throttle, it is likely running lean which is not good. and the poor ecu is constantly trying to adjust fuel to compensate. I would stay out of open loop or you may hurt something.
Have you followed Cory's recommendation in how to find a leak? You likely loosened or cracked something or pulled a vacuum hose when cleaning the MAF.
But why were you cleaning the MAF? You must have had something wrong beforehand to cause you to do that.
Do you have all the mods when you were tuned? If not, that is likely the issue possibly combined with a leak of some form.
Try putting the stock intake back on.
