Haha that's my style right there.

Did you mask it off at all or just peel the plasti-dip in the places you didnt want covered?

The only thing I could see being an issue is the 3" downpipe, since your exhaust wheel is 3.25" it could end up being a choke point.

I had the same problem the other day. Serial to USB adapters are awful.

I believe you can take the idle valve apart and unscrew the plunger all the way. Then put it back together and it should stay that way as long as you don't have any power to it. Maybe stack washers up on the shaft so It can't retract again under boost.

TB set screw backed out enough to keep the TB closed?

The idle valve is there but not connected, would it still cause an issue even though its not connected?

And yea, tb is all the way closed

Sounds like it's hunting for idle and can't control it. Plug iac in and see what it does. I believe off/unplugged position is wide open which may explain.
