Sputtering Under Wot
My cars been having a problem where its sputtering under wot and been slugglish in the higher rpms. I had an o2 sim installed, reset the ecu and installed a nwp bop today and its pulling a lot better. Problem is around 5-5.5k rpm, the car begins sputtering and hesitates accelerating any further. I have no idea what the problem could be, and can make a video if needed to explain what Im talking about.
Mods: Car has intake, headers, bop, and an exhaust.

Filter is pretty much brand new. Its a spectre 3" filter.
The car has no CEL/SES lights.
It was doing this prior to the o2 simulator. I thought the o2 simulator would fix the problem but that doesn't seem to be the case. Ill take the maf out next and clean it with some maf cleaner and see if that helps out at all.

Might want to check for any air leaks, also have you been burning oil even a bit higher than normal? if so you may have a cat getting clogged up ... bad fuel or clogged injectors, might want to try some seafoam in your next fill up of gas ... just a couple of thoughts that also come to mind ... cleaning the MAF sensor is a good place to start.

I know its a pain to check but number #5 (under the manifold) and closest to the driver side of the car have been know to get full of oil.
As T_Behr has mentioned if the plugs are getting old it may just be time to swap them all out and breath some fresh life back into the engines spark.
