i've had VTCS removed for about 5 months now. i actually just tried to swap it with someones stock one so Juan could do more accurate tuning for the 6's kit. but for some reason my car doesn't like the stock one anymore?? won't idle at all with it in place?? I'm swapping mine back on Sat morning hoping she'll like that better.
As far as removing the IM, i've done it a good 10 times now and it only took me 11 minutes to remove it this morning (though i think i have more room in the 6 than the 3 has?). doing all the tweaking took about an hour, mostly just trying to figure out what to do. and a bit more time to seal things up and let the stuff dry.
with it removed, especially in cold weather, cold starts are a bit scary. very irratic breathing until it warms up. feels really good above 4500 though, it's only a small improvement, but hey, it was pretty much free.
