Lean @ WOT

[HLxDrummer]

Ya I didn't think about ignition.. that would throw off the wideband readings as well. Does it pull smoothly though? And would that be inconsistent?

even at .28 and 12.5 psi O_o? Plugs were changed a month ago.

No ignition = no combustion = lean AFR.

Riching the AFR only compounds the issue.

I guess I'll change plugs again, maybe try out these gapless ones Chris is selling... might as well do wires this time around too. Should have spare coils/ptu around somewhere to try if the plugs and wires dont fix it.

Last resort is msd or hks box T_T really dont wanna buy one

It doesnt pull smooth throughout. There is a slight stutter at wot, you can barely feel it but you can hear it.

swapped ptu and coils, no change

Did you also change plugs/wires? You could put the boost to wastegate and see how it runs. Shouldn't get blow out at 6 PSI I wouldn't think..

I would consider putting the old throttle body back on and a stock tune (or the one you had before).

Also, have you pressure tested? I wouldn't recommend tuning the ECU to "fix" the trims as it is just a bandaid fix. I would try to fix the mechanical issue throwing off the trims.

swapped aem fpr for oem frp, problem solved

pressure obviously high as hell but this can be tuned around.

Thanks for the input guys

edit: flashecu trims have to be tuned for regardless because of all the mods, - 0 leaks as of today

Glad you found it! You can also go with a Fuel Lab one. I've heard of people having issues with the AEMs.
