Inlets and meth, what to expect?

Has anybody gone from fbo to fbo +inlets/meth? How did you like the change? Where did you feel the biggest difference?

You need a custom tune or appropriate backend based on fuel + custom tuned map 6 boost curve. The principle is removing the restriction allows boost to be cranked up on the top end. No off the shelf boost map is going to take full advantage of the inlets although you should still see an improvement with shelved high boost maps/tunes and inlets.... So they say.
