i still am having trouble tuning my car....i have the basic ct-26/lexus/580cc/walbro/apex-i. I cannot no matter what i do get my AFRs at idle to stay put. It always fluctuates from like 14.4-16.0. It never stays still. Is this becasue it's a piggyback system and not a standalone??

I have a standalone and mine does the same thing. If this is unacceptable then I'm in the same boat as you. There was a thread about this about a week ago.

Its called O2 cross counts and its normal operation.
The only time you will see a constant is at WOT.
