Also, what is the difference between this custom build kit and Weistec Meth Kit ?
Is it noisy ?
I am also in Canada, which city are you in ? east or west ?
$1500 is not expensive at all with all those power gain.
Hopefully, everything goes smoothly for you.
Question what BOV did you buy, would extremely appreciate the help on which one fits the car right.
I also bought a killerchiller want to see how both work together.
I drive a CLS with a few mods.
I noticed that I had to do something for my IAT, that's why I want to do the above mentioned mods :-)
Great to see likeminded meth guys here Hahaha

That's only an issue on MAF cars. M157 use speed/density strategies. If you have the right spring in it, it is closed at idle and only vents on boost transition to vacuum on decel.
As for nozzle location, I tend to agree that pre intercooler in the V seems counter productive. I think that weistec and others were just trying to do creative packaging when they put it there. I was thinking post TB on the Intake manifold as it makes the 180 transition, but not sure that will be picked up by the IAT sensor. If going direct into the IM , you need a solenoid based system to avoid potential leak issues. Ideally I think pre-turbo Plus direct in the IM would yield most benefits.
