More TIG practice. The 3" aluminum tube running from the intercooler outlet to the TB inlet never fit well because the junction was at a ~ 20 degree angle and I made up the difference with a silicone joiner. I decided to fix that and bought a 22 degree bend and welded it to the (shortened) tube from the intercooler. You can also see the little box I fabbed up to shield the ECU from heat and moisture (though the Haltech is supposedly waterproof)
Definitely getting better at this but I still need lots of practice. The more major stuff I have planned (fresh-air anti-lag) will require stainless welding and backpurging, and I don't have a second argon bottle and reg so I'll have to go to Larry's to do it.
