Does it get fatter in the middle when you add primary? What are your WOT duty cycles?

Default Well post logs dude...

Oh and I'd check fuel pressure if you can. What size MAF housing, what type of sensor? Stock fuel pump? Replaced fuel filter? Using a 5bar FPR?

Default You need to give more details than that if you want somebody to really put effort into helping.

Jason and Andy both are asking good questions. If the answer to Jason's question is yes, could be fuel pump (assuming injectors aren't physically maxxed)...seen this on a few cars including my own. A sign of this would be both primary 02s dropping as RPMs rise:

No annoyance. AW and S4 related e-mail are the ultimate breaks from school work.

Default that's what i am in the middle of doing right now......

i tried replacing the fuel filter the other day and got to the point where i needed a 12 point 8mm and was SOL, so i had to put everything back together.

i'm starting with the fuel filter adn then going with the pump. i am running a converted (hitachified) 83mm RS4 maf with a 4bar.

I PROMISE to post more detailed posts about this in the very near future...i've just been burnt out lately from beating my own brains.

thanks to all!
