Apologies...I do not know why the address differs now. Try it now... it is a fresh copy + paste  
Also, you can be creative with your own spray method including selecting your own product and delivery canister.
Just be sure to completely seal the space in the IAT port if your canister comes with a small diameter dispensing tube. Drilling a small hole through a small rubber cork that fits the port will allow for use of a prepackaged product.

Can you confirm what solution you use and how much of it. Thanks

I use 1 part fuel, 1 part NAPHTHA(quick drying solvent), and 2 parts white spirits...at least 16oz minimum.

Here is a new vid I made showing the mixture and my sprayer mods:

This looks awesome! Where does the carbon build-up go? I've seen in your video it appears to come out of the exhaust. Could this cause any damage to a 200 cell sports cat?

I did this when my exhaust was stock and when I had a 400cell ceramic cat. So it does pass through the system safely...at least with mine, and I haven't heard of any horrible tales. I am catless now and there is never carbon debris on my concrete following this procedure...so it must burn quite thoroughly during combustion.
