Lean

It's probably the tune but ever since I put longtubes on after my dyno tune it's been running lean. I've tried adjusting fuel pressure and everything else but seems like in the video the computer is trying to fix it self but runs lean. I'm trying to post the video of my wide band but it won't let me

At idle it jumps from 14-17 and up till the idle smooths out then it sits at the 3 red lines (indicates very lean)and will go back and forth

Since your car has been tuned it might need to be tweaked by the tuner.


At idle your car uses fuel and timing to control the idle. It is a constant adjustment of up and down of both of those items.

Yeah that's what I figured because you can tell the computer is trying to correct it but it's fighting the tune. Thanks man!
