BAH!! Smoke from my 5" tapered stainless tip behind the rear wheel looks awesome. It covers ricers better that way.

Sealboy - There are plenty of mods to help you get to the smoke level. I accomplished it with a chip and stock injectors. Good that you got the 6637 intake. You should also get rid of the factory downpipe and cat, do the fuel pressure shim and get EGT and boost gauges (tranny temp too if it's auto). The wicked wheel upgrade for your turbo is the stock turbo impeller for the earlier 7.3s, which is pretty funny if you think about it! If you have the cake, go for stage I or even II injectors, with a chip tuned for them. Best tuners are either Tony Wildman or DP. I still have my Banks chip, which is actually tuned pretty well, but a TW is coming soon. You can find out all about what you need by going to the 7.3 boards on this site.

Or you could belch smoke real easy and cheap if you want. Just put a Walmart plastic bag around your 6637!
