I went with meth over the intercooler (a labonte system). I would to anyone that asks. You need to do something at those boost levels. For the most part an intercooler will be a more complex install and more expensive. I don't mind having to fill the meth once every week or two. It's just 0 degree windshield wiper fluid.
You must drive the piss out of your car. That's a lot of meth.
