the ECU upgrade and boost jets should not effect idle...
probably a sensor problem...run an ECU diagnostics. i doubt anythign will come up being the check engine light isnt on but its worth a try.
now go through and wiggle your TPS sensor harness. that sensor is a common problem with these cars...
i have a couple mroe ideas for you 2 but you should start witht he most common. for now, if it is doing this constantly, then you can adjust the Idle Adjustment Screw to bump the idle up a bit.
and Idle is supposed to be around 700rpms in neutral.
