There aren't any discernible noises at this point that would make me think vacuum leak, but I'll report back after having a go at that adaptation.

For the ported iABED it was just a little overzealous indeed. Seems like we clipped the plate a little with the die grinder so I assume that's where the whistle came from. It ran with the ported TB on it, it was just a bit annoying so I bought that replacement. When I changed to the new throttle body that's when it started the newer idle thing, but I also changed the SC at that point as well. The blower was tested by the guy who ported it and I'm pretty confident it doesn't stem there, unless maybe I hooked a hose up to the wrong place when reinstalling, but it seems pretty straight forward.

So APR has their ultracharger tune, but it is only available if you buy their ultra charger which is way over priced. I ran the Iabed throttle body for about 4 months and had no issues with the tune. I just put it in and drove.

I'll pull some codes with my MPVI2 and see what happens. Will report back.


do you still have old throttle body that whistled? i would try reinstalling that and see if idle settles. if not id think something with supercharger or install since then that would-be the only change
