after i got my turbo kit together it seemed to idle fine, until after i drove it for a while. after the cars been warmed up the idles will drop very low and will sometimes feel like it is about to die out.

here's my setup:

94 usdm b18c1
t3/t4e .63 a/r 57 trim
ssac manifold
3" open downpipe

fuel management:
rechipped p28 w/ uberdata on basemap
dsm 450cc w/ resistor box
walbro 255 fuel pump

-spark plugs are gapped to .030
-at stock ignition timing
-no vacuum leaks
-coolant is fine

video clip of shitty idling:
5.1 mb .AVI

notice how the idle drops to almost 100 rpms and the vac is only at like 15 in/hg. it only does this after the cars been warmed up to operating temps.

any ideas?

 

Its idleing funny because you are running on a basemap, get it tuned and im sure you will be fine
