pc3 once again

[dober]

Hi guys ,long time member and lurker.
I am running bolt-ons with a marble mod plus a pc3. I am trying to get rid of a surging at low rpm say about
3600 -4000 rpms.
Is this surging caused by a lean or a rich condition ?or
both ??
thanks

It's lean...custom map is the best cure

Ya didn't hear it from me but a TRE will help too

Custom map would be very nice but it would be about $500Canadian and very hard to justify to the wife ;(

The Hindle map seems very strong, but surges at very small constant throttle ..I`ll keep playing and add fuel from 3700 -4000 rpms. thanks
