Did ya gents have to adjust your bypass's my cold idle is bad as it is lean and jumps all over hell and I wonder if adjusting it will help... warm the car and it will actually rev better but still not great and idle surch goes down to about 100rpm. Showing roughly 5 inch's of vac at 750 rpm. Just seams when I adjust the TB screw up it does nothing then jumps 400 rpm all at once to 1200rpm yet my pms still unused but hooked up still says the tps is in idle. I have a stage 1 tfs cam.
I was told not to touch the bypass. If you think it's the bypass you could hook up a hose to the vacuum port, and suck on it to see if it takes an unusual amount of vacuum to open, but I doubt that is your problem, unless someone already screwed with it.

Unplug the IAC and see if anything changes. Mine was bad and I didn't even know it, until it was on the dyno.
