A/F gauge playing?!

i just got my turbo installed last week. the PCM is tuned and everything seems to be OK but the A/F gauge, its still playing around, its only stable when i turn my truck on but keeps playing between lean and rich when i'm driving. ive got the Autometer A/F gauge that comes from STS Turbo.

maby the engine is surging? unless its actually a wideband i wouldnt really trust it. i would datalog while driving and watch the gauge and see what rpm its doing it and then check out the datalog at that rpm.

If it is the autometer gauge that just has the red, yellow, and green lights on it that scrolls back and forth, then its not telling you anything. It's just a pretty light show.

thats normal operation for it to go back and forth....as it is reading the 02's and they are constantly cycling back and forth

under WOT...the lights should move to the right and hold...might increase a lil or decrease..depending on your tune
