No I don't. I have an intercooler in the works, but its not installed and has not been installed ever on my car. The way things look because of how busy I am, I may not even get the chance to put on the IC this year at all.

I've restricted boost by not going smaller than a 3.2" pulley but as an everyday car, I run around with a 3.4" pulley. This winter, I am going up to a stock pulley and to heck with power (gas prices are just CRAZY!!). Having both a Pulley Boys quick change setup and an awesome custom made pulley puller (designed to apply as much as 28-30 tons of pull force if needed), helps for these kinds of things.

Bottom line... I can run 87 because of my supporting mods (cam, headers, etc...), I've tuned for it and not gone nuts on the boost end.
