Ok, well the dyno didn't go well at all. Started leaning out hard in higher rpms. I need to back up a bit to make sense of everything for those with the same problems.
First start the engine ran lean, all the time. I thought the stock fpr was bad and installed a nismo fpr.
That didn't change anything.
I found out the maf was too close to the turbo, moved it.
That changed the lean idle to a Intermittent issue.
On the dyno, car ran super lean the whole time, lean in boost, lean idle, tip-in/light throttle sucked. Gave up and went home.
I have a problem letting things go, so I start thinking again.
Put the stock fpr in.
No more lean idle.
Went for a drive, no lean issues at all, then the car dies and won't start. T start to trace wires and find the maf signal wire at the ecu had 1 thread connecting it. I find the ecu connector loose as well.
Drive home happy, get home and find a massive exhaust leak where the DP meets the cat. That explains the dyno's afr's reading leaner than my innovate WB.
Plugs before on the Right, plugs after the Dyno on the Left:
The exhaust leak was making it seem leaner that it was, it was lean, just not THAT lean.
Going back to the dyno to verify it's all good.
